Hi!

Please can anyone explain to me the step by step procedure to replace a faulty FC drive on a DS2405 attached to a rp7410 with two fc controllers.

Hi!

From what I understood that document is related to replacing any drive with respect with O.S., first I believe that I have to use commands like fcmsutil to isolate the disk: that's the part that I dont understand.

It just works as a normal SCSI disk.

No need to isolate the disk

Hi!

Sorry again, look what I've been told, please correct:

1. # fcmsutil /dev/td1 get remote all
2. look for target state=DVS_UNOPENED
3. Note Nport ID
4. # fcmsutil /dev/td1 replace_dsk get remote all
5. Now use the procedure described on the link supplied by you.

Here is an overview about the steps (I assume you will do this online with HP-UX):

- locate the failed disk
- replace it
- run ioscan (you will see it stiil as NO_HW)
- view syslog file
- run fcmsutil /dev/tdx replace_dsk 0xnnnn
- run ioscan again (CLAIMED)
- restore the LVM config and sync the mirror
