Configuring the Solaris Environment

After physically installing the disk drive, you must create a new device entry for the drive in the /devices, /dev/dsk, and /dev/rdsk hierarchies. The new drive is assigned a logical device name of the form cwtxdysz, where:

• w corresponds to the SCSI controller for the disk drive

• x corresponds to the SCSI target for the disk drive

• y is the logical unit number for the disk drive (always 0)

• z is the slice (or partition) on the disk

The logical device name assigned to the drive depends on the disk slot number where the drive is installed as well as the PCI slot number that contains the disk's associated UltraSCSI controller card.

1. Use the drvconfig and disks commands to add the new device:

   ---

   # drvconfig
   # disks
   

   ---

2. To verify that the new disk has been created, type:

   ---

   # ls -lt /dev/dsk | more

   The new disk and its logical device name appear at the top of the list. Check the file creation date to make sure it matches the current time and date. In the example above, the logical device name for the new disk is c0t3d0.
