Solaris 10 What's New

Solaris support for LSISAS1064 RAID Operations

This device management feature is new in the Solaris 10 6/06 release.

The raidctl utility creates, deletes, and displays Redundant Array of Inexpensive Disks (RAID) volumes of the LSI1030 and LSI1064 controllers. This utility also updates firmware, fcode, and BIOS for LSI1030 and LSI1064 controllers. The raidctl utility requires privileges controlled by the underlying file system permissions. Only privileged users can change the RAID system configuration. If a non-privileged user attempts to create or delete a RAID volume, the command fails with EPERM.

The LSI1030 SCSI Host Bus Adapter (HBA) supports a single RAID volume. This volume is a two-disk mirror, which is also known as Integrated Mirror (IM). IM volume is a RAID 1 type volume. An IM volume can be created on an LSI1030 controller only if the secondary disk has a capacity greater than or equal to the primary disk and there are no file systems mounted on the secondary disk.

The LSI1064 HBA can enable up to two RAID volumes, IM and Integrated Stripe (IS). The IS volume is a RAID 0 type volume. To create a volume on the LSI1064 controller, member disks of the volume should not have mounted file systems because volume initialization destroys data on member disks.
