Solaris & Scripting: Solaris 10 x86 SVM Patching

Solaris 10 x86 SVM Patching
Solaris 10 SVM Patching (x86)

Step 1: Backup the necessary configuration file and save it
df -h
metastat -p
metadb
echo | format
prtconf -v | sed -n '/bootpath/{;p;n;p;}'
Root Disk - c0t0d0
Root Mirror Disk - c0t1d0
6 copies of metadb replicas - c0t0d0s7 and c0t1d0s7
Current Kernel - 147441-01

Step 2: Detatch the submirrors and clear them
/dev/md/dsk/d0 /
/dev/md/dsk/d1 swap
/dev/md/dsk/d3 /var
/dev/md/dsk/d4 /opt/BMC

     JUDI-DEV-TEST01# metastat -p
     d4 -m d14 d24 1
       d14 1 1 c0t0d0s4
       d24 1 1 c0t1d0s4
       d3 -m d13 d23 1
       d13 1 1 c0t0d0s3
       d23 1 1 c0t1d0s3
       d1 -m d11 d21 1
     d11 1 1 c0t0d0s1
       d21 1 1 c0t1d0s1
       d0 -m d10 d20 1
     d10 1 1 c0t0d0s0
       d20 1 1 c0t1d0s0
       JUDI-DEV-TEST01#
metastat -p
metadetach d0 d20
metadetach d1 d21
metadetach d3 d23
metadetach d4 d24

metastat -p

metaclear d20
metaclear d21
metaclear d23
metaclear d24

metastat -p

Step 3:   Remove replicas added on root mirror disk
metadb
metadb -d c0t1d0s7
metadb

Step 4:   Install grub on root mirror disk to make sure the disk is bootable incase we want to back-out the patching
installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t1d0s0

Step 5:   Mount root Mirror disk c0t1d0s0 on mnt
mount /dev/dsk/c0t1d0s0 /mnt
df -h /mnt

Step 6:   Modify /mnt/etc/vfstab & /mnt/etc/system files
cat /mnt/etc/vfstab
vi /mnt/etc/vfstab
/dev/dsk/c0t1d0s1 - - swap - no -
/dev/dsk/c0t1d0s0 /dev/rdsk/c0t1d0s0 / ufs 1 no -
/dev/dsk/c0t1d0s3 /dev/rdsk/c0t1d0s3 /var ufs 1 no -
/dev/dsk/c0t1d0s4 /dev/rdsk/c0t1d0s4 /opt/BMC ufs 2 yes -

tail /mnt/etc/system
vi /mnt/etc/vfstab (Comment the mirror related information)
* Begin MDD root info (do not edit)
* rootdev:/pseudo/md@0:0,0,blk
* End MDD root info (do not edit)
* set md:mirrored_root_flag=1

Step 7:   Delete existing boot sign on root mirror disk and create unique one
ls -l /mnt/boot/grub/bootsign/
-r--r--r-- 1 root root 0 Oct 17 2013 rootfs0

rm /mnt/boot/grub/bootsign/rootfs0
touch /mnt/boot/grub/bootsign/rootfs1
ls -l /mnt/boot/grub/bootsign/

Step 8:   Update root mirror disk menu.lst file
ls -lrt /mnt/boot/grub/menu.lst
cat /mnt/boot/grub/menu.lst

      Edit the file and change the rootfs0 to rootfs1 in both lines and change the title as Root Mirror Disk
  vi /mnt/boot/grub/menu.lst
  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title Root Mirror Disk Oracle Solaris 10 8/11 s10x_u10wos_17b X86
  findroot (rootfs1,0,a)
  kernel /platform/i86pc/multiboot
  module /platform/i86pc/boot_archive
  #---------------------END BOOTADM--------------------
  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title Solaris failsafe
  findroot (rootfs1,0,a)
  kernel /boot/multiboot -s
  module /boot/amd64/x86.miniroot-safe
  #---------------------END BOOTADM--------------------

  cat /mnt/boot/grub/menu.lst

Step 9: Update boot environment variable on root mirror disk
  echo | format
  cat /mnt/boot/solaris/bootenv.rc
  ls -ld /dev/dsk/c0t1d0s0
  lrwxrwxrwx 1 root root 62 Oct 17 2013 /dev/dsk/c0t1d0s0 -> ../../devices/pci@0,0/pci8086,3c06@2,2/pci1028,1f38@0/sd@1,0:a
  vi /mnt/boot/solaris/bootenv.rc
  setprop bootpath '/pci@0,0/pci8086,3c06@2,2/pci1028,1f38@0/sd@0,0:a' ----> Remove this line
  setprop bootpath '/pci@0,0/pci8086,3c06@2,2/pci1028,1f38@0/sd@1,0:a' ----> Add the secondary disks path here

Step 10: Update boot disks menu.lst file,
This step will allow us to skip the step of configuring BIOS to boot from root mirror disk
  cat /boot/grub/menu.lst
Edit the file and make entry to list out the secondary disk as separate boot disk while grub booting screen comes
Add the below entry to the bottom of the file - secondary disk - rootfs1
  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title Root Mirror Disk - Oracle Solaris 10 8/11 s10x_u10wos_17b X86
  findroot (rootfs1,0,a)
  kernel /platform/i86pc/multiboot
  module /platform/i86pc/boot_archive
  #---------------------END BOOTADM--------------------
  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title Solaris failsafe
  findroot (rootfs1,0,a)
  kernel /boot/multiboot -s
  module /boot/amd64/x86.miniroot-safe
  #---------------------END BOOTADM--------------------

Step 11:   Check the currently booted device
  prtconf -v | sed -n '/bootpath/{;p;n;p;}'
Currently server booted from root disk, Now restart and boot from root mirror disk
  init 6
Server will display as
creating boot_archivee for /mnt
updating /mnt/platform/i86pc/boot_archive

while rebooting slect the root mirror disk from grub menu - to check the root secodary disk is safe to boot.
Check from which disk the server is booted and make sure the disk booted from root mirror - now we are good to proceed patching
  prtconf -v | sed -n '/bootpath/{;p;n;p;}'

Step 12: Reboot the server to boot from boot disk see the root disk status
  init 6
Check from which disk the server is booted and make sure the disk booted from boot disk - Primary disk
  prtconf -v | sed -n '/bootpath/{;p;n;p;}'

Step 13:   Bring the server into single user mode and install the patches
  who -r
  init s

Step 14: Start install the patches
  ./installpatchset --s10patchset

Step 15: Patch installation completed, Reboot the server
  init 6
Verify the new patch version and smf status
  uname -v
  svcs -xv
  df -h

Step 16: Now create submirrors and replicas on root mirror disk
  echo | format
  metstat -p
  metainit -f d0 1 1 c0t1d0s0
  metainit -f 21 1 1 c0t1d0s1
  metainit -f 23 1 1 c0t1d0s3
  metainit -f 24 1 1 c0t1d0s4

Step 17: Attach submirrors to the main mirror
  metadb -afc3 c2t0d0s7
  metadb
  metstat -c

  metattach d0 d0
  metattach d1 d21
  metattach d3 d23
  metattach d4 d24

  metastat -c
Wait until the resync completes

  uname -X
  metastat -c d0

Once the resync completed, Reboot the server
  init 6
