Re: Add missing disk to hardware raid
Thank you for your reply!!
The disk is free to replace the missing drive, but I'm not sure about the command syntax for replacement.
Should I be using io_redirect_dsf?
In addition, when I add the disk to the array, will it rebuild off of the existing without data loss?
Thank you again for your help

Re: Add missing disk to hardware raid
Thank you again for the response.
I have removed the structure from the disk
pvremove /dev/rdsk/c0t1d0
I have physically removed the disk and rebooted.
I removed remaining special files, rebooted again.
rmsf -x
re-installed disk while system is up and check status which was again the same as above.
NOTE: (we have other rx6600s and rx3600s that do rebuild automatically when replaced live)
There is something unusual...
drvcfg -s from EFI shell will not let me view "Raid Properties" says inactive
I will look deeper into this and get back in a few days.
THANK YOU for your quick replies and awesome help!!!

Re: Add missing disk to hardware raid
disk on bay 0 is missing (part of the mirror for logical drive 7), the disk for raid0 as logical drive 5 is missing too.
If you now want to use this disk from ld 5 for ld7 it only works if you delete the logical drive, otherwise you only "move" logical drive 5, because the information about logical drive config is still stored.
Deleting data from OS on the logical drive does not change anything.
What disks and how many disks are currently inserted?
Only 1?
Hope this helps!
Regards
Torsten.

Re: Add missing disk to hardware raid
Good Morning,
I really appreciate your patience.
2 drives inserted:
Enclosure 1 Bay 7 (boot disk)
Enclosure 1 Bay 8 (unused disk)
I was hoping to use Enc 1 Bay 8 (unused disk) as the missing RAID 1 mirror disk of (LD7)
Thank you again
