Bug Description
OS: Ubuntu 12.04.1 64-bit Server Edition, Installed from CD
Machine: Supermicro custom build, Intel motherboard, Megaraid SAS 9861-8i
Drive config: Megaraid configured with two arrays, one of SSDs and one of HDDs.
1. Configured RAID card to present two virtual drives from arrays.
2. Began installation from Ubuntu CD
3. Get the message "Server RAID has been detected, do you want to activate it?"
4. Regardless of which option is chosen, the result is the same:
"Ubuntu did not find any disks. Do you want to configure an iSCSI mount?"
5. Go back to Disk Detection
6. Ubuntu is unable to detect disks.
7. Try selecting modules from the modules list. All selections fail. Tried:
megaraid
megaraid_sas
This appears to be the same issue reported in bug #546091, which was supposedly resolved in the 12.04.1 update. However, as reported on that bug, the update does not seem to have resolved the problem for any reporting user.
Note that both CentOS 6.2 and Gentoo seem to mount the megaraid automatically, with no issues at all, using the megaraid_sas module.
