18) How do you create additional state databases in solaris volume
manager? -- This was the tough one..!!
19) Does Solaris Volume Manager have soft partitioning?
20) How do you clear volume information from a solaris volume manager
disk?
21) How do you shutdown a Veritas Cluster Server, leaving the
applications running from the command line?
22) How do you speed up processing of a process and All it's child
processes? -- This was quite tricky..!!

14. When you "ping server" and "ping server.domainname", you get different results. Why?
15. Someone pings a server from another location and gets a different result than if you ping the same server onsite. What is going on?
16. You know the reason the server won't boot is because of ODS, but the root partition isn't on ODS. How do you go about fixing it?
17. How would you truncate a log file that is growing too large if you don't have space to compress it or to move it somewhere else? How would you do it "hot"?
18. When the key is in the lock position on a Sun Enterprise server, can you do a Stop-A? Explain.
19. What does "boot -a" do?
20. What is uadmin and what does it do?
21. What does "ypwhich servername" do? Why would you use it?

How to configure/ reconfigure SmartArray RAID Controller
How to configure/ reconfigure the Internal RAID card on an HP-RX6600 Server with HP-UX
Here is an example, screenshot where I reconfigured a mirrored disk set.
There are totally 8 disks in the server and each 2 disks are mirrored.
The Logical drive number-2 has been deleted to get 2 free disks.
Note:
Check on OS side which disks are assigned to whatever volumes and double check if there is no DATA on the disks before performing this delete operation.

HP-UX - How to convert Strict/Distributed to normal Volume
use this following website to view and discuss and post about various UNIX related issues and break fixes. please share your views.
http://unixadvice.formyjob.net/forum.htm
How to convert Strict/Distributed volumes to normal.
Some times the HP engineers will create the volumes with strict / distributed instead of doing striping in the volume manager. We may not have enough disks to extend the volumes, in that case we can remove the strict allocation and make the volume as normal volume.
To turn off the Distributed allocation policy:
# lvchange -D n /dev/vg02/lvol1
That can be done online. After that you should be able to do your lvextend.
Change the allocation policy of a logical volume to nonstrict:
#lvchange -s n /dev/vg01/lvol7
HOST2@root:/> lvdisplay -v /dev/vgsap/test |more

How to convert Strict/Distributed volumes to normal.
Some times the HP engineers will create the volumes with strict / distributed instead of doing striping in the volume manager. We may not have enough disks to extend the volumes, in that case we can remove the strict allocation and make the volume as normal volume.
To turn off the Distributed allocation policy:
# lvchange -D n /dev/vg02/lvol1
That can be done online. After that you should be able to do your lvextend.
Change the allocation policy of a logical volume to nonstrict:
#lvchange -s n /dev/vg01/lvol7
