Solaris 10 - Steps to create LDOM

Steps to create LDOM

1. Create Domain

# ldm add-domain spup-lx-v01
# ldm add-vcpu 16 spup-lx-v01
# ldm add-mem 8g spup-lx-v01
# ldm list

Note: Record /etc/resolv.conf, /etc/netmasks, /etc/inet/ntp.conf file entry from same server environment.
You will need this info to set up this VM.

2. List some ldom related info
# ldm list
# ldm list-services
# ldm list-bindings
# ldm list-bindings spup-lx-v01

3. Add vnet to LDOM
# ldm add-vnet vnet0 primary-vsw2 spup-lx-v01
# ldm add-vnet vnet1 primary-vsw3 spup-lx-v01

We are configuring multi-pathing
# ldm set-vnet linkprop=phys-state vnet0 spup-lx-v01
# ldm set-vnet linkprop=phys-state vnet1 spup-lx-v01

4. Add Disk

# ldm list
# echo | format | grep -i <LUN>

# ldm add-vdsdev /dev/dsk/c0t6000D310006D6400000000000000023Cd0s2 DL30@primary-vds0
# ldm add-vdisk VDL30 DL30@primary-vds0 spup-lx-v01

Set boot device variables
# ldm set-var boot-device=vdl30 spup-lx-v01
# ldm set-variable auto-boot\?=false spup-lx-v01

# ldm list-bindings spup-lx-v01

5. Bind and start the LDOM

# ldm bind spup-lx-v01
# ldm list spup-lx-v01
# ldm start spup-lx-v01
# ldm list spup-lx-v01

6. Login to console
# telnet 0 5008

{0} ok boot -s

7. Once you login, perform the following tasks.

a. Remove /etc/path_to_inst (rebuilding device tree).
# mv /etc/path_to_inst /var/tmp/222._etc_path_to_inst
# rm /etc/path_to_inst*

b. Network and hostname configuration
Add hosts entry with correct IP/HOST
# vi /etc/hosts
192.168.10.60   spup-lx-v01.sces.dev    spup-lx-v01     loghost

# vi /etc/netmasks

192.168.1128 255.255.255.128
192.168.10.0    255.255.255.128

# cat >/etc/hostname.vnet0
spup-lx-v01 netmask + broadcast + group ipmp up

# cat >/etc/hostname.vnet1
group ipmp up

# ifconfig vnet1 up

dns client set up
# vi /etc/resolv.conf

domain sces.dev
search sces.dev
nameserver 192.168.10.24
nameserver 192.168.10.29

- Set up default router
# cat /etc/defaultrouter
192.168.1129

# cat >/etc/nodename
spup-lx-v01

# cat /etc/nodename

# hostname

# vi /etc/inet/ntp.conf
server 192.168.10.24

# ls -l /var/ntp/ntp.drift

# more /etc/hosts.allow
rpcbind: 192.168.10. 192.168.1. 192.168.5.
sshd: ALL
sendmail: localhost 127.0.0.1

# more /etc/nsswitch.conf

# ls -ltr /etc | grep path_to

# reboot -- -r

spup-lx-v01 console login:

# more /etc/resolv.conf
domain sces.dev
nameserver 192.168.10.24
nameserver 192.168.10.29

# cat /etc/netmasks
192.168.10.0    255.255.255.128

# cat /etc/inet/ntp.conf

server 192.168.10.14

# ldm list-spconfig
# ldm add-spconfig cfg07012015

Record /etc/resolv.conf, /etc/netmasks, /etc/inet/ntp.conf file entry

Redhat 7 - Puppet installation

Client installation

1. Update hosts file with puppet server if DNS is not working
# vi /etc/hosts
214.38.138.239 spup-lx-v02     spup-lx-v02.expanor.local

wq
# ping spup-lx-v02.expanor.local

2. Update PATH variable
# vi /root/.profile
PATH=/usr/bin:/usr/sbin:/usr/local/bin:/usr/ccs/bin:$PATH:/opt/puppetlabs/puppet/bin
export PATH

wq!

# . /root/.profile

3. Use curn to download and install the agent package

# curl

When puppet client try to make a connection to pupper server first time, it generate a certificate and pass it to puppet server to sign in. The certificate need to signed manually at the server side.

To resolve this issue,
Go to puppet master server and perform the following command to list all certificates that are waiting for sign.

# puppet cert --list | more
"sidm-mw-v18.expanor.local" (SHA256) 7D:0D:3A:0E:B7:14:9E:72:E5:6D:75:10:70:C1:1E:5A:CD:03:B2:5C:55:88:E8:86:2D:43:AE:C3:C6:E3:EA:B0

Now, we can see the certificate from client waiting for signing.
Run the following command below to sign the certificate.

[root@spup-lx-v02 ~]# puppet cert sign sidm-mw-v18.expanor.local
Signing Certificate Request for:
"sidm-mw-v18.expanor.local" (SHA256) 7D:0D:3A:0E:B7:14:9E:72:E5:6D:75:10:70:C1:1E:5A:CD:03:B2:5C:55:88:E8:86:2D:43:AE:C3:C6:E3:EA:B0

[root@spup-lx-v02 ~]#

if you want to sign all certificates, run the command below,
# puppet cert sign --all

you get this error.

Any Puppet agent connecting to a Puppet master server for a first time will generate a certificate and give it to a Puppet master server to sign. Depending on your puppet configuration, a default behavior is that the certificate must by signed manually and thus puppet agent exits with an error:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Puppet Implementation

Prerequisites
- Root Access
- Server with 2 cores, 6 GB RAM
- 20 GB of free space available under /opt
- Ensure port 3000 is open.

Puppet Enterprise Installation

1. Download Tar ball version ending in -el-<version arch>.tar.gz.
2. Run the following command to unpack the tarball:
   # tar –xzf <tarball>
3. To set up the installer, Run
   # sudo ./puppet-enterprise-installer
4. When prompted, choose the “Guilded” installation option.
5. The PE installer will start a web server at
   https://<hostname>:3000
6. Log onto PE Console and create password for admin user and fill the remaining info and continue.

Puppet Agent Installation

1. In the console, click Nodes > Classification. On the Classes tab, select the class that matches your client.
2. Click Add Class and commit changes.
3. From the command line on Puppet Master, run puppet agent –t.
4. SSH into your agent node and run:
   # Curl –k https://<master_server>:8140/packages/current/install.bash | sudo bash
5. The installer installs and configures the Puppet Enterprise Agent.
6. After installation is complete, approve the certificate request from the Request Console from the puppet server.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Enterprise Puppet Master is only supported on a Linux based Platform. Redhat Enterprise Linux is selected because it’s DOD Common Criteria (CC) certified. Puppet will be used for system baseline and configuration management.

For Puppet Enterprise Server to communicate with clients on TEST & DEV Enclaves, the following firewall changes needs to be implemented:

Source: TEST 214.38.139.128/25
                DEV   10.222.102.0/25

Target: spup-lx-v02.expanor.local (214.38.138.239)
Ports:
   8140 -- Puppet Master Inbound Port
   61613 – Mcollective Port
   4433 – Classifier/Console Services API Port
   8081 – PuppetDB Port
   8142 – Orchestrator Port
   8143 – Orchestrator/PCP Broker Port

Puppet will be used to deploy system security baseline and configuration managements.

RedHat Enterprise Linux 7.0 (Puppet Master)
Solaris 10/11 (Puppet Agents Only)

Detailed Description Of Proposed Change
1. Build a VM running Redhat Enterprise Linux 7.x
2. Install Enterprise Puppet on Redhat VM.
3. Deploy Puppet Agents to Solaris systems.
4. Test communication and deployment pushes between Puppet Master & Client Agents.

Test Documentation

Create a sample Class for NTP under /opt/puppet/classes/ntp.mod

class { '::ntp':
servers   => ['dev-ad1.sces.dev', 'dev-ad2.sces.dev'],
restrict => [
    'default ignore',
    '-6 default ignore',
    '127.0.0.1',
    '-6 ::1',
    'ntp1.corp.com nomodify notrap nopeer noquery',
    'ntp2.corp.com nomodify notrap nopeer noquery'
],
}

To test if sample ntp file gets push, Run:
Sudo puppet apply --test

Verify sample test modules created from PE Consoles gets successfully pushed out to Puppet Clients.

Back-out Plan

1. Shutdown Puppet services from Master server.
2. Disabled Puppet Agents on clients.

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only"                                                        and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package                                                       -cleanup can help).

Solaris - SPARC T7 Console login

SPARC T7 Console login
1. Plug the power cords from the AC power source to the rear of the server.

2. Connect a device to the SER MGT port.

3. Connect a terminal or a terminal emulator (PC or workstation) to the server SER MGT port.

4. Configure a terminal or terminal emulator with these settings:

9600 baud
8 bits
No parity
1 Stop bit
No handshake

Note: null modem configuration is needed, meaning the transmit and receive signals are reversed
(crossed over) for DTE to DTE communications. You can use the supplied RJ-45 crossover
adapters with a standard RJ-45 cable to achieve the null modem configuration.

5. Connect an Ethernet cable between the server's NET MGT port and
the network to which future connections to the SP and host will be made.

6. Connect an Ethernet cable between one of the server's NET ports and the
network to which the server will communicate.

7. Power on the System for the First Time

8. At the terminal device, log in to the SP.

login: root
Password: changeme

->

ILO default user name and password:- root/changeme
[ -> is ILOM prompt ]

9. Power on the server using the command below
-> start /SYSTEM

If you want to stop the power on process, type #. (hash+DOT keys) and at the ILO prompt type
-> stop /SYS

10. To redirect host output to display on serial terminal device type
-> start /HOST/console

Some parameter change

From ILOM, set the OpenBoot auto-boot? parameter to false.
-> set /HOST/bootmode script="setenv auto-boot? false"

to reset the system from the ILO prompt
-> reset /SYS
-> start /HOST/console

At ok prompt
{0} ok help boot

Assign a Static IP Address to the NET MGT Port

1. Connect to the ILOM on the SP using the SER MGT port.
-> set /SP/network pendingipdiscovery=static
-> set /SP/network pendingipaddress=service-processor-IPaddr
-> set /SP/network pendingipgateway=gateway-IPaddr
-> set /SP/network pendingipnetmask=255.255.255.0

Verify the parameters if set correctly.

Solaris 10 - autofs set up

autofs

On nfs server perform the following tasks

1. Add entry to dfshare
# vi /etc/dfs/dfstab
share -F nfs /data/mydb/test/myshare

2. Share your directory
# shareall

3. Verify your share
# share
- /data/mydb/test/myshare rw ""

4. List the directories under the share
# ls -R /data/mydb/test/myshare
/data/mydb/test/myshare:
test

/data/mydb/test/myshare/test:
best

/data/mydb/test/myshare/test/best:
bishal

/data/mydb/test/myshare/test/best/bishal:

Now, go to your client system

1. Add entry to auto_master file for direct map
# vi /etc/auto_master
/- auto_data -browse

2. Add entry for direct map on auto_data file
# vi /etc/auto_data
/dbdata/OS_Image1 192.168.10.21:/data/mydb/test/myshare

3. Run automunt command to update the share to be managed by automount
# automount -v

4. Restart autofs
# svcs -a | grep autofs
online 10:20:06 svc:/system/filesystem/autofs:default
# svcadm restart autofs

# cd /dbdata/
# ls
OS_Image1
# cd OS_Image1/
# ls
test
# cd test/
# ls
best
# cd best/bishal/

ls -R /dbdata/OS_Image1
/dbdata/OS_Image1:
test

/dbdata/OS_Image1/test:
best

/dbdata/OS_Image1/test/best:
bishal

/dbdata/OS_Image1/test/best/bishal:

# df -h .

192.168.10.21:/data/mydb/test/myshare 872M 453M 419M 52% /dbdata/OS_Image1

Solaris 10 - working with nfs server and client

Nfs share

1. Create the directory you want to share
# mkdir /data/mydb/test/myshare

2. Share your directory
# share -F nfs /data/mydb/test/myshare
# share
- /data/mydb/test/myshare rw ""

Now, go to the client and mount

On client system
1. Check if your system has access to the share

# showmount -e 192.168.10.21
export list for 192.168.10.21:
/data/mydb/test/myshare (everyone)

2. Mount the share
# mount 192.168.10.21:/data/mydb/test/myshare /mnt

3. Verify the share
# df -h /mnt
Filesystem size used avail capacity Mounted on
192.168.10.21:/data/mydb/test/myshare 872M 453M 419M 52% /mnt
#

Now on your server, check what/which clients are using your share.
# cat /etc/rmtab
# cat /etc/rm
rmmount.conf rmt rmtab
# cat /etc/rmtab
# cat /etc/rmtab
# cat /etc/rmtab
# vi /etc/dfs/dfstab

Solaris 10 - Adding swap device ufs partition, zfs volume and ufs file as swap device

A. Adding UFS partition as a Swap device

1. Create partitions

# format c1t0d0

# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344

2. Add partition as a swap device

# swap -a /dev/dsk/c1t0d0s1
# swap -a /dev/dsk/c1t0d0s3
# swap -a /dev/dsk/c1t0d0s4
# swap -a /dev/dsk/c1t0d0s5

3. List swap device
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/dsk/c1t0d0s1 33,65 8 409592 409592
/dev/dsk/c1t0d0s3 33,67 8 409592 409592
/dev/dsk/c1t0d0s4 33,68 8 204792 204792
/dev/dsk/c1t0d0s5 33,69 8 204792 204792

4. Remove swap device
# for i in /dev/dsk/c1t0d0s1 /dev/dsk/c1t0d0s3 /dev/dsk/c1t0d0s4 /dev/dsk/c1t0d0s5
> do
> swap -d $i
> done
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344

B. Adding zfs volume as a swap volume

Create zfs mirror and create swap device using zfs filesystem

1. Remove the sub mirror from the pool
# zpool detach datapool c1t2d0
# zpool status datapool
pool: datapool
state: ONLINE
scan: resilvered 454M in 0h0m with 0 errors on Sun Jun 4 09:00:42 2017
config:

NAME STATE READ WRITE CKSUM
datapool ONLINE 0 0 0
c1t0d0 ONLINE 0 0 0

errors: No known data errors

2. Mirror the disk
# zpool help attach
usage:
attach [-f] <pool> <device> <new-device>
# zpool attach datapool c1t0d0 c1t2d0

3. Create a swap volume
# zfs help
The following commands are supported:
allow clone create destroy diff get
groupspace help hold holds inherit list
mount promote receive release rename rollback
send set share snapshot unallow unmount
unshare upgrade userspace
For more info, run: zfs help <command>
# zfs help create
usage:
create [-p] [-o property=value] ... <filesystem>
create [-ps] [-b blocksize] [-o property=value] ... -V <size> <volume>
# zfs create -V 100m datapool/myswap

4. Locate your swap volume
# ls -l /dev/zvol/dsk/datapool/myswap
lrwxrwxrwx 1 root root 35 Jun 4 09:09 /dev/zvol/dsk/datapool/myswap -> ../../../../devices/pseudo/zfs@0:1c
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
datapool 557M 419M 32K none
datapool/mydb 454M 419M 453M /data/mydb
datapool/mydb/test 31K 419M 31K /data/mydb/test
datapool/myswap 103M 522M 16K -
mypool 142K 1.95G 31K none
mypool/opt_os 31K 1.95G 31K /opt/os
yourpool 189K 19.6G 31K none
yourpool/FS_opt-OS_Image 31K 19.6G 31K /opt/OS_Image
yourpool/fs-opt-os 31K 19.6G 31K /opt/os

5. Add swap
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
# swap -s
total: 273784k bytes allocated + 91588k reserved = 365372k used, 1264948k available
# swap -a /dev/zvol/dsk/datapool/myswap
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792
# swap -s
total: 273868k bytes allocated + 91572k reserved = 365440k used, 1366508k available
#

c. Adding file as a swap device

1. Create 100 MB of swap device
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792

# mkfile 100m /data/mydb/myswap

2. List current swap devices that are on use
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792

# swap -s
total: 273868k bytes allocated + 91572k reserved = 365440k used, 1267308k available

3. Add swap file as swap device
# swap -a /data/mydb/myswap
"/data/mydb/myswap" may contain holes - can't swap on it.

Since this is zfs filesystem, you can create number of swap volume.

lets try ufs filesystem

1. Create 100MB of file
# df -h /
Filesystem size used avail capacity Mounted on
/dev/dsk/c0d1s0 8.1G 4.0G 4.0G 51% /

# mkfile 100m /myswapfile

2. List currently used swap devices
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792
# swap -s
total: 273868k bytes allocated + 91572k reserved = 365440k used, 1263380k available

3. Add swap device
# swap -a /myswapfile
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792
/myswapfile - 8 204792 204792
# swap -s
total: 273868k bytes allocated + 91572k reserved = 365440k used, 1365776k available

Solaris 10 - Creating zfs filesystem detail

Creating zfs filesystem

1. Find your disk to use for pool
# echo | format

2. Create a pool
# zpool create ppool c2t1d0

3. Create filesystem
# zfs create ppool/FS_opt-os

4. Mount the filesystem
# zfs set mountpoint=/opt/os ppool/FS_opt-os

1. Find your disk to use for pool
# echo | format

or
# zfs create -o mountpoint=/opt/os mypool/opt_os
or
# zfs create ppool/FS_opt-os
# zfs set mountpoint=/opt/os ppool/FS_opt-os

or
# df -h /opt/ns
ppool/fs_opt_ns 20G 31K 20G 1% /opt/ns
# zfs umount ppool/fs_opt_ns
# zfs set mountpoint=/opt/OS_Image ppool/fs_opt_ns
# df -h
# zfs mount ppool/fs_opt_ns

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

How to change mount point on zfs

1. Check your mount point that you are going to change
# df -h /opt/OS_Image/
Filesystem size used avail capacity Mounted on
ppool/fs_opt_ns 20G 31K 20G 1% /opt/OS_Image

2. Unmount old mountpoing
# zfs umount ppool/fs_opt_ns

3. Verify filesystem is unmounted
# df -h /opt/OS_Image/
Filesystem size used avail capacity Mounted on
/dev/dsk/c0d1s0 8.1G 4.0G 4.1G 50% /

4. Check zfs filesystem
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
pool 85K 976M 31K /pool
ppool 142K 19.6G 31K none
ppool/fs_opt_ns 31K 19.6G 31K /opt/OS_Image

5. Change the mountpoint
# zfs set mountpoint=/opt/ns ppool/fs_opt_ns

6. Verify its changed
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
pool 85K 976M 31K /pool
ppool 142K 19.6G 31K none
ppool/fs_opt_ns 31K 19.6G 31K /opt/ns

# df -h /opt/ns
Filesystem size used avail capacity Mounted on
/dev/dsk/c0d1s0 8.1G 4.0G 4.1G 50% /

7. Mount the filesystem and verify
# zfs mount ppool/fs_opt_ns
# df -h /opt/ns
Filesystem size used avail capacity Mounted on
ppool/fs_opt_ns 20G 31K 20G 1% /opt/ns

zfs mirror and creating swap on zfs filesystem

1. Remove the sub mirror from the pool
# zpool detach datapool c1t2d0
# zpool status datapool
pool: datapool
state: ONLINE
scan: resilvered 454M in 0h0m with 0 errors on Sun Jun 4 09:00:42 2017
config:

NAME STATE READ WRITE CKSUM
datapool ONLINE 0 0 0
c1t0d0 ONLINE 0 0 0

errors: No known data errors

2. Mirror the disk
# zpool help attach
usage:
attach [-f] <pool> <device> <new-device>
# zpool attach datapool c1t0d0 c1t2d0

3. Create a swap volume
# zfs help
The following commands are supported:
allow clone create destroy diff get
groupspace help hold holds inherit list
mount promote receive release rename rollback
send set share snapshot unallow unmount
unshare upgrade userspace
For more info, run: zfs help <command>
# zfs help create
usage:
create [-p] [-o property=value] ... <filesystem>
create [-ps] [-b blocksize] [-o property=value] ... -V <size> <volume>
# zfs create -V 100m datapool/myswap

4. Locate your swap volume
# ls -l /dev/zvol/dsk/datapool/myswap
lrwxrwxrwx 1 root root 35 Jun 4 09:09 /dev/zvol/dsk/datapool/myswap -> ../../../../devices/pseudo/zfs@0:1c
# zfs list

yourpool/FS_opt-OS_Image 31K 19.6G 31K /opt/OS_Image
yourpool/fs-opt-os 31K 19.6G 31K /opt/os

5. Add swap
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
# swap -s
total: 273784k bytes allocated + 91588k reserved = 365372k used, 1264948k available
# swap -a /dev/zvol/dsk/datapool/myswap
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d1s1 102,1 8 1076344 1076344
/dev/zvol/dsk/datapool/myswap 181,1 8 204792 204792
# swap -s
total: 273868k bytes allocated + 91572k reserved = 365440k used, 1366508k available
#
