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. 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:
ok printenv boot-device
boot-device =
ok devalias disk
disk
2. Type the boot net –s command.
ok boot net –s
