To Create A Hardware Mirrored Volume Of The Default Boot Device - Fujitsu SPARC Enterprise T2000 Administration Manual

The following example shows that the RAID mirror is synchronized and online.
# raidctl

c0t0d0
The disk controller synchronizes IM volumes one at a time. If you create a second IM
volume before the first IM volume completes its synchronization, the first volume's
RAID status will indicate RESYNCING, and the second volume's RAID status will
indicate OK. Once the first volume has completed, its RAID status changes to OK, and
the second volume automatically starts synchronizing, with a RAID status of
RESYNCING.
Under RAID 1 (disk mirroring), all data is duplicated on both drives. If a disk fails,
replace it with a working drive and restore the mirror. For instructions, see
Perform a Mirrored Disk Hot-Plug Operation" on page
For more information about the raidctl utility, see the raidctl(1M) man page.
▼ To Create a Hardware Mirrored Volume of the
Default Boot Device
Due to the volume initialization that occurs on the disk controller when a new
volume is created, the volume must be configured and labeled using the format(1M)
utility prior to use with the Solaris Operating System (see
Hardware RAID Volume for Use in the Solaris Operating System" on page
Because of this limitation, raidctl(1M) blocks the creation of a hardware RAID
volume if any of the member disks currently have a file system mounted.
This section describes the procedure required to create a hardware RAID volume
containing the default boot device. Since the boot device always has a mounted file
system when booted, an alternate boot medium must be employed, and the volume
created in that environment. One alternate medium is a network installation image
in single-user mode (refer to the Solaris 10 Installation Guide for information about
configuring and using network-based installations).
