▼ 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
“Configure a Hardware
RAID Volume for the Solaris OS” on page 22 ). 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.)
1. Determine which disk is the default boot device.
From the OpenBoot ok prompt, type the printenv command, and if necessary
the devalias command, to identify the default boot device. For example:
2. Type the boot net –s command.
3. Once the system has booted, use the raidctl(1M) utility to create a hardware
mirrored volume, using the default boot device as the primary disk.
See “Create a Hardware Mirrored Volume” on page 15 . For example:
ok printenv boot-device
boot-device = disk
ok devalias disk
disk /pci@0/pci@0/pci@2/scsi@0/disk@0,0
ok boot net –s
# raidctl -c –r 1 c1t0d0 c1t1d0
Creating RAID volume c1t0d0 will destroy all data on member disks,
proceed (yes/no)? yes
...
Volume c1t0d0 is created successfully!
