How can boot from Sec if you are removing it?


To find boot disks:
Shell> map â r â fs â b

To boot from fs0:
Shell> fs0:
fs0:>hpux -lq

Sorry for junk chars...

To find boot disks:
Shell> map -Â Â r -Â Â fs -Â Â b

Ooh...my fault.

It is:
Shell> map -r -fs -b

You need to properly remove "Secndory Disk" information from the OS level" by "lvextend -m 0" and vgreduce I believe later you cannot put back the disk,

Hi R.K,

Shell> map -r -fs -b >>

will it display sec disk path like fs1: ?

HI,

i think better you can split the lvs instead of lvreduce. So it wont make any impact on second disk. If anything goes wrong we can rebulid it by lvmerge command.
Please let me know why did not you plan for ignite recvoery image, as i mentioned earlier its very easy and wont take more than 2 hours. Its very neccessary to rebulid the system when the server got crash.

Shell> map -r will show the mapped devices from there you can identify the sec boot disk by using H/W path.

for make_net_recovery you have to verify the lan card whether it is lan boot supported. You can verify it by using server user guide or let me know the server model number.
