You can use TABLE 3-1to associate internal disk slot numbers with the logical and physical device names for each hard drive.

TABLE 3-1Disk Slot Numbers, Logical Device Names, and Physical Device Names

Disk Slot Number

Logical Device Name*

Physical Device Name

Slot 0

c0t0d0

/devices/pci@7c0/pci@0/pci@8/scsi@2/sd@0,0

Slot 1

c0t1d0

/devices/pci@7c0/pci@0/pci@8/scsi@2/sd@1,0

 

 

 

*The logical device names might appear differently on your system, depending on the number and type of add-on disk controllers installed.

▼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. 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 =

disk

ok devalias disk

 

disk

/pci@7c0/pci@0/pci@8/scsi@2/disk@0,0

2.Type the boot net –scommand.

ok boot net –s
