Upgrade Veritas Storage foundation 4.1 to 5.0 on Sun Solaris

All right, After a long time I finally back on blog. Little busy with my house shifting work and setting it up along with managing office work... It was real busy week... Today I have a task of Veritas Volume Manager/Veritas Storage Foundation upgrade work so thought having this information on the blog.

let me admit before I start - I am not an expert on this product and have very small experience with this product.

I am upgrading Veritas Storage foundation 4.1 to 5.0 on Sun Solaris 5.9, below steps guide on "how to?"

1. Save your existing configuration at some safe location. This document does not consider rootdg as we dont use rootdg at all. What we will concentrate on is datadg.

Lets see what is current Veritas Volume Manager version is -

# pkginfo -l VRTSvxvm
PKGINST: VRTSvxvm
NAME: VERITAS Volume Manager, Binaries
CATEGORY: system
ARCH: sparc
VERSION: 4.0,REV=12.06.2003.01.35
BASEDIR: /
VENDOR: VERITAS Software
DESC: Virtual Disk Subsystem
PSTAMP: VERITAS-4.0_MP2_RP7.2:2007-02-22
[.....]

or you can use command -

# pkginfo -l VRTSvxvm |grep VERSION |awk '{print $2}' |awk -F, '{print $1}'

Before upgrade make sure you save your current configuration like license file, vfstab file, df -kh O/P, mount command's O/P and few VxVM commands output like vxprint, vxdisk list, vxdg list etc... This information will help you in case of upgrade fail and backout process.

# cd /etc/vx/licenses/; tar -cvf /home/nilesh_rjoshi/vx_licenses_101109.tar ./* >>>> Take backup of VxVM licenses

# cp -p /etc/vfstab /home/nilesh_rjoshi/ >>>> Backup vfstab file.

# df -kh > /home/nilesh_rjoshi/df_kh_op_101109 >>>> df -kh output

# mount > /home/nilesh_rjoshi/mount_op_101109 >>>> mount command output

# vxprint -ht > /home/nilesh_rjoshi/vxprint_ht_op_101109 >>>> Save vxprint -ht output. vxprint utility displays complete or partial information from records in VERITAS Volume Manager (VxVM) disk group configurations.

# vxprint -g datadg -mvphsrqQ > /home/nilesh_rjoshi/vxprint-g_datadg_mvphsrqQ_op_101109 >>>> In detail O/P of vxprint command

# vxdisk list > /home/nilesh_rjoshi/vxdisk_list_op_101109 >>>> Save O/P of vxdisk, it shows all disks associated with or used by VERITAS Volume MAnager.

# vxdg list > /home/nilesh_rjoshi/vxdg_list_101109 >>>> Backup the data group list

Nice one, I guess now we have enough information backed up and can be used in case of backout if something goes wrong.

Let us start with the upgrade process.

Before proceeding ask application users to stop their applications or if you have authority and knowledge on how to stop applications then please disable Applications & Unmount filesystems.

Below three steps needs to be carried out -

- umount vxfs filesystems
- comment them out of the vfstab
- disable application startup in /etc/rc2.d and /etc/rc3.d

# df -kh
/dev/md/dsk/d0 3.0G 2.4G 481M 84% /
/proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
fd 0K 0K 0K 0% /dev/fd
/dev/md/dsk/d3 2.0G 1.6G 334M 83% /var
swap 11G 160K 11G 1% /var/run
dmpfs 11G 0K 11G 0% /dev/vx/dmp
dmpfs 11G 0K 11G 0% /dev/vx/rdmp
/dev/md/dsk/d6 992M 8.2M 925M 1% /home
/dev/md/dsk/d5 2.0G 362M 1.5G 19% /tmp
/dev/vx/dsk/datadg/app1_vol
5.0G 2.6G 2.3G 54% /app1
/dev/vx/dsk/datadg/app_db_vol
1.0G 452M 536M 46% /app_db
/dev/vx/dsk/datadg/appdata_vol
40G 10G 28G 28% /app_data
[.....]

# umount /app1; umount /app_db; umount /app_data

Verify if with df -kh to see everything is fine.

# vi /etc/vfstab >>>> Comment out veritas filesystems in vfstab file.

Now disable application startup in /etc/rc2.d and /etc/rc3.d

# mv S90app_tomcat K90app_tomcat

Make sure you have comment out entries in vfstab file for all veritas filesystems, application auto startup is stoped through rc directories, and all veritas filesystems are un-mounted. Next task is export the diskgroup.

# vxvol -g datadg stopall >>>> The vxvol utility performs VERITAS Volume Manager (VxVM) operations on volumes. This is Maintenance command for VERITAS.

# vxdg deport datadg >>>> Disables access to the specified disk group. A disk group cannot be deported if any volumes in the disk group are currently open. When a disk group is deported, the host ID stored on all disks in the disk group are cleared (unless a new host ID is specified with -h), so the disk group is not reimported automatically when the system is rebooted.

# vxdg -t import datadg >>>> Dissassocaite dg from host. Where -t for a temporary name. import option imports a disk group to make the specified disk group available on the local machine.When a disk group is imported, all disks in the disk group are stamped with the host's host ID.

# vxdg deport datadg

Fine, now we are done with all applicable operations on disk group.

Start the installer/upgrader:

Mount the CD/ISO file on the server and start the installation.

Quick note on mounting ISO file on Solaris -

# lofiadm -a /nilesh_rjoshi/VERITAS_Storage_Foundation_5.iso
/dev/lofi/1
# mount -F hsfs /dev/lofi/1 /mnt


Navigate to location
# cd /mnt/Solaris/Veritas/v5.0/sf_50_base

NOTE: BE SURE YOU'RE IN RUNLEVEL 3, THIS WILL NOT WORK IN RUNLEVEL 1

# ./installer

Do the appropriate clean-up and start installer once again.

So make sure your root filesystem has enough space available.

Installer will now stop the process and will install MP1. Basically this will install several Sun patches required for VERITAS packages. It is just a process of fixing bugs!

Add the mp1_rp3 [VRTSvxvm 5.0MP3RP2: Rolling Patch 02 for Volume Manager 5.0MP3]

# cd /mnt/Solaris/Veritas/v5.0/sf_50_mp1_rp3/

# patchadd 123742-04

# patchadd 124361-04

Once all this done the re-import the diskdg

# vxdg import datadg

# vxdg deport datadg

# vxdg import datadg

# vxvol -g datadg startall

Verify with

# vxprint -ht >>>> Verify that the volumes are ENABLED/ACTIVE

Final touchup

Renable filesstems in /etc/vfstab
Re-enable application startup in /etc/rc2.d/ /etc/rc3.d
verify you can mount all filesystems in vfstab with "mount -a"
reboot system one final time: init 6 or shutdown -y -i6 -g0

Here you done. This upgrade is pretty straight forward if everything is good like enough disk space on root, var and tmp, system is well patched etc...

Hope it will be a useful information for someone! Have a great weekend.
