Micha,
Thank you for taking the time to reply to my very long message.
Regarding your statement, "I consider the current configuration as
dead..."
Currently, the RAID 5 is operational and in degraded status. I did
completely botch the drive replacement once and had to rebuild the
raid and restore from backup as described in my previous message. But
right now I am hoping to retry the drive replacement on the correct
drive this time. So do you still consider the current config as dead
with the RAID still operational?
No, my comment was for the original one. Seems that I don't have read
your message correctly.
As I wrote, I recommend to set the IDs with Jumpers. You can also try to
do this with the current configuration. Probably the Adaptec firmware
will accept changed IDs and detect the disks for your RAID by their
signatures.
Then set the array to degraded state manually (by removing one drive
from the configuration with the setup tool). If you don't have set the
IDs with Jumpers, access the RAID now and the LEDs on the disks will
tell you which disk was disabled. Now you know what drive you have to
touch and you can replace it physically. The RAID must stay in degraded
state and you can rebuild it now.
Simply try, all you can lose is the time for restoring the backup again.
But you hopefully know how your disks are configured and how the
controller works at the end.
I would call Adaptec, but my support period for this product is over
and they won't even accept email support at this point.
But a manual for the controller should exist on Adaptecs Inet server.
You should find a description how to correctly disable a drive before
physically removing it there.
