3–6 HSG80 ACS Solution Software Version 8.6 for Compaq Tru64 UNIX Installation and Configuration Guide
Preparing LUNs for Access by Tru64 UNIX
FileSystem
Tru64 UNIX treats an HSG80 LUN much like a SCSI disk; therefore, to prepare your
LUN for access by the Tru64 UNIX filesystem, you must do the following:
■ Create the partitions on the LUN using disklabel
■ Create a filesystem on the LUN
■ Mount the filesystem to be able to access it
Creating Partitions on a LUN Using disklabel
Create the partitions on a LUN by issuing a disklabel command. The disklabel command
partitions the LUN for access by the Tru64 UNIX Operating System. Tru64 UNIX defines
only partitions a, b, c, and g for the HSG80 controller. In addition, refer to the rz and
disktab man pages for more information about the disklabel utility.
To create the read/write partitions on a LUN using the default partition sizes, enter the
following:
For V4.0G
# disklabel -rw device HSG80
Where:
■ HSG80 defines this LUN as attached to the HSG80 array controller. Always use the
device label HSG80 regardless of what drive types make up the LUN.
■ device is the character device name.
For example, to create partitions on block device, rza8, enter:
# disklabel -rw rza8 HSG80
For V5.1x
# disklabel -rw disk HSG80
Where:
■ HSG80 specifies the type of disk as found in /etc/disktab or the driver for that device.
■ disk is the character device name found in /dev/rdisk.
