Regarding active disk replacement

[Kavita Poonia]

Hello,

I have a disk which has gone bad but it is in CLAIMED state so I want to get it replaced with HP. Can anyone please let me know what exact steps, I need to follow before and after replacing disk. The disk is mirrored too.

Thanks & regards,
Kavita

Hi Kavita,

The above mentioned doc "good disk go bad" is the best doc you can refer for disk replacement.

Still I am attaching a procedure for disk replacement in PA-RISC (you have not mentioned you server model)....but always keep the "good disk...." doc.

Regds,
R.K.

Hi,

If it is a system disk, then you need to boot the system, with out quoram with
boot -lq

you need to remove the disk from vg00 and add a new disk and mirror it.

Thank you all for your replies and docs. I do have that Good disk go bad pdf. I have read that but in case the disk which I want to replace is in available status and is a internal device, is in root VG but not a bootable disk, mirrored with few PEs on one disk in root VG and few PEs on another disk which is also in same VG. There are 4 internal disks in root VG and out of that 3 are configured as bootable which is maximum we can have on a server and the disk in question here is forth one which is not bootable. It is a bit quite complicated structure.

Shardha: Are you sure that I need to boot my server for this. I do not think so.....
