Snap4100 "Logical set member not found"

jhrBanker · 01-18-2006, 07:41 AM

Can anyone help?
I am unable to access files on my SNAP M4100.
The error message says; "Logical set member 2 not found"
Disk Status: Data Protection disabled. One RAID 5 member
has failed. Operating in degraded mode.

Does this mean I've lost my data? Any way to recover it?
What should I do?

Thanks in advance for any help you can provide.

If what i remember Raid 5 being is true

Ie 2 drives and one for parity, that lets you rebuild the dead drive

IT would seem not, the dead drive should be replacable and it should rebuild the raid set

It all depends on how the array was setup. You are able to rebuild an array if you fail one drive. 2 drive failure is non recoverable. The replacement drive should match the failed drive. There is a debug cmd to initate a rebuild. It may even be in the disk utility with the web interface.

I read an knowledge base article on Adaptec site on this problem.
It said to install a replace hd, format, then make it the spare. Apparently a spare will auto join an array that needs repair.
