Full Discussion: Raid5 Failure
Operating Systems SCO Raid5 Failure Post 99769 by Perderabo on Tuesday 21st of February 2006 11:56:16 AM

All drives in a raid 5 should generally be identical and must be identical in size. I don't know what an adaptec controller is, but when you replace the drive, you must rebuild the lost info. I would expect any utility to lead you in that direction. A backup would be wise.

NAME

       lsimega - SCSI HBA driver for LSI MegaRAID 320-2x SCSI  RAID Controller

       The lsimega SCSI RAID  host bus adapter driver is a SCSA-compliant nexus driver that supports LSI MegaRAID 320-2x SCSI RAID devices.

       The  lsimega  driver supports  standard	functions provided by the SCSA interface, including RAID disk I/O  and	passthrough I/O to support
       SCSI tape and CDROM.

DRIVER CONFIGURATION

       The lsimega.conf file contains no user configurable parameters. Please configure your hardware through BIOS.

       The LSI MegaRAID 320-2x device can support up to 40 logic drivers. Note that BIOS numbers the logic drives as  1  through  40,  however	in
       Solaris these drives are numbered from 0 to 39.
