Disk array

Disk array

I have two FC1010ds with 36 GB dirves Mirrored
between both enclosures. I have one dead drive which I have reduced out of the mirror so the system is up and the file system is mounted. the question is I a replace the drive with the file systems mounted ( am I hot pulgable ) or will this cause a SCSI bus reset ?

Re: Disk array

Just plug in the disk.
Do an ioscan (will present you still NO_HW) and take a look into /var/adm/syslog/syslog.log
now do a

fcmsutil /dev/tdx replace_dsk 0xyyyy

with the proper values. Do an ioscan again and you will see the disk CLAIMED.

If you vgreduced the disk, pvcreate and vgextend the disk. If not, vgcfgrestore the config. Now re-activate the VG and mirror again.

Hope this helps!

Torsten.

Re: Disk array

Thanks, I did not vgreduce the drive:
I did vgchange -a y -q n /dev/vg01. This allowed me to mount the remaining drive without ots mirror partner. So after the drive is seen Ishould just vgcfgrestore the Volume Group and vgchnage -a y -q y and finally vgsync... ?

Re: Disk array

Replace the disk and do the fcmsutil. After the disk is becoming CLAIMED, do a vgcfgrestore and a vgchange -a y vg01 and resync the vg.
Check with vgdisplay -v vg01.

Hope this helps!
