How to recover Raid configuration on Mac

[sonc3]

I have a Direct Attached Stroge and create 2 Luns on it (27TB + 27 TB). we had stopped the system. When we started it again, we couldn’t find the RAID vol. There are two LUNs but there no RAID volume showing up. Is there a way to recover the RAID volume on the Mac?

Ask Nanofrog as he knows a lot about RAIDS.. AFAIK, any RAID other than RAID 0 can be recovered.. but here its just that you stopped the system and turned it back on and now its not showing up. Try to zap the PRAM(OPT+CMMD+P+R). That might help it to re-appear.

You can also boot up the system in single-user mode and type: /sbin/fsck -fy - This tries to fix problems with the file system and overall disk itself.

Otherwise, ask Nanofrog.
