I'm trying to install CentOS 5 IBM Netfinty 5000. I recently rebuilt the RAID setup and now it looks like this:
- logical drive 1: 2x4GB RAID 1
- logical drive 2: 3x9GB RAID 5
When i try to boot from CentOS cd i get the following message.
Code:
Cannot open root device "(NULL)" or unknown-block(253,0)
Please append a correct "root=" boot option
Kernel Panic - not syncing : VFS : Unable to mount root of on uknown-block(253,0)
Note that the server was working perfect with CentOS 4 for a long time.
when i boot into IBM's RAID utility (which is a linux little distro by the way), the utility tells me that everything is alright. My disks are online , arrays are healthy and should be working like a champ.
i tried to boot "linux rescue" hoping i could modify some options but it's getting back to the same error. Any suggestions?
