Patching 11.23 with QPK08 using DrD and a 2 disk scenario
This procedure, breaking a mirror to use as clone disk, IS NOT RECOMMENDED BY HP, but if like me, you only have 2 disks on the system, you have no other choice.
Install the latest version of DrD on your Server(no reboot needed), you can download from:
http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNu...
#swinstall -s s:/var/opt/ignite/depot/Rel_B.11.23/software/updates DynRootDisk
Update the drd_unsafe_patch_list file (if necessary):
Update the unsafe patch list as follows:
i) Download the ftp://ftp.itrc.hp.com/export/DRD/drd_unsafe_patch_list file to /etc/opt/drd/drd_unsafe_patch_list on your active system image.
If you have not created a clone, then you are done with updating the drd_unsafe_patch_list file and have finished this procedure. If you have created a clone, continue with Step ii.
ii) Because DRD uses the copy of the drd_unsafe_patch_list file on the inactive system image, the copy on that image must also be updated. If there is a clone, mount the inactive system image:
# /opt/drd/bin/drd mount
iii) If there is a clone, copy the drd_unsafe_patch_list file to the inactive system image:
# /usr/bin/cp /etc/opt/drd/drd_unsafe_patch_list \
/var/opt/drd/mnts/sysimage_00*/etc/opt/drd/drd_unsafe_patch_list
Once we have DrD installed, we have to take out one of the mirror disks to use as drd clone disk:
#vgdisplay -v vg00 | grep "PV Name"
PV Name /dev/dsk/c0t8d0s2
PV Name /dev/dsk/c0t10d0s2
We are going to take out of the mirror /dev/dsk/c0t10d0 disk:
#for i in $(pvdisplay -v /dev/dsk/c0t8d0s2 | grep 'current.*0000 $' | awk ' { print $3 } ' )
#do
#lvreduce -m 0 $i /dev/dsk/c0t10d0s2
#done
Once all the PE's in the disk are free, we reduce vg00:
#vgreduce vg00 /dev/dsk/c0t10d0s2
And edit the /stand/bootconf, taking out the reference to /dev/dsk/c0t10d0s2 disk:
#vi /stand/bootconf
Update the LABLE on the disk:
#lvlnboot -vR /dev/vg00
We are ready to clone the disk we launch a preview, to check all is OK:
#drd clone -x overwrite=true -p -v -t /dev/dsk/c0t10d0

======= 07/01/09 15:00:17 METDSTDST END T Clone System Image Preview succeeded. (user=root) (jobid=sdppbus1)
The clone preview worked fine, so now we can do the actual clone:
#drd clone -x overwrite=true -v -t /dev/dsk/c0t10d0

======= 07/01/09 15:54:23 METDSTDST END T Clone System Image succeeded. (user=root) (jobid=sd)
Once it has finished we can check , the state of the clone:
#drd status

All looks ok, we can install our patches, the bundle we install is one, I have made that contains the Dec 08 quality pack, plus other loose security patches:
#swlist -s sdp:/var/opt/ignite/depot/Rel_B.11.23/patch-bundles/dec08/
# Contacting target "sdp"...
#
# Target: sdp:/var/opt/ignite/depot/Rel_B.11.23/patch-bundles/dec08/

We can execute the drd runcmd command as follows:
# drd runcmd swinstall -x
autoselect_patches=true
-s sdp:/var/opt/ignite/depot/Rel_B.11.23/patch-bundles/dec08/ PARCHES_DEC08

..................
More information may be found in the agent logfile using the
command "drd runcmd swjob -a log sd-0153 @ sd:/".
======= 07/02/09 08:38:22 METDSTDST END T Executing Command On Inactive System Image failed with 1 error. (user=root)
I get an error so I check the swagent logs:
#drd runcmd swjob -a log sd-0153 @ sd:/
After checking the error, everything worked fine except and error with a vxvm patch, wich I can ignore.
So now I activate my clone Image, so it boots when we reboot the server:
#drd activate
Now we plan a reboot, so our operators can reboot the server at 2:00 AM, and with luck tomorrow morning we will have a new patched server.
After the reboot, and giving the patches a couple of weeks testing, I recreated the mirror with our not patched disk.
Finished.
