Replace failed disk

Can some help with step by step instructions/commands to replace failed disk if it is mirrored or not.

Our controller is HSZ80.
Thanks in advance

Re: Replace failed disk

Is your failed disk mirrored on the HSZ80 or using LSM at the UNIX level. The replacement instructions are quite different for the two situations.

Re: Replace failed disk

It is not LSM. I did show failedsets and it shows: uses-disk41000 useby-- none, autospare

shoe disks--
disk4100 4 10 0 failedset

Does this help your question?
Thanks,

Re: Replace failed disk

I would hope this problem has long since been addressed!

Anyway, the Unix version, while likely to be Tru64, are pretty much irrelevant.

This is more of a hardware question than software. One needs to understand the HSZ to deal with this. Rather then describing here folks facing this should study the appropriate "HSOF User Guide"
For example around page 115 in this online version:
http://www.xenya.si/sup/info/digital/MDS/jun99/Cd3/STORAGE/CLI70RMA.PDF

Now if is is a non-redundant logical unit it will of course loose all data, and may in fact be re-created. If the logical drive is recreateed, then there is some Unix work needed. It will come back with a new WWID and thise a new dskxxx name.
Use:
hwmgr scan scsi
hfmgr show scsi
adapt /etc/fdmns and-or /etc/fstab to the new name.
optionally rename the new dsk device with dsfmgr

hth,
