The following example shows that the RAID mirror is synchronized and online.
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 60
.
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 55
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).
