■ SECTORS_PER_TRACK—the number of sectors per track used. The range is
from 1 to 255.
Specifying Unit Switches
Several switches control the characteristics of units. The unit switches are
described under the SET unit-number command in the HP StorageWorks
HSG60 and HSG80 Array Controller and Array Controller Software Command
Line Interface (CLI) Reference Guide.
One unit switch, ENABLE/DISABLE_ACCESS_PATH, determines which host
connections can access the unit, and it is described in the larger topic of matching
units to specific hosts. This topic is described in Chapter 1, “Determining
Connections” on page 42.
Creating Storage Maps
Configuring a subsystem will be easier if you know how the storagesets,
partitions, and JBODs correspond to the disk drives in your subsystem. You can
more easily see this relationship by creating a hardcopy representation, also
known as a storage map.
To make a storage map, fill out the templates provided in Appendix A as you add
storagesets, partitions, and JBOD disks to the configuration and assign them unit
numbers. Label each disk drive in the map with the higher levels it is associated
with, up to the unit level.
Using LOCATE Command to Find Devices
If you want to complete a storage map at a later time but do not remember where
the disk drives and partitions are located, use the CLI command
LOCATE. The
LOCATE command flashes the (fault) LED on the drives associated with the
specific storageset or unit. To turn off the flashing LEDs, enter the CLI command
LOCATE CANCEL.
The following procedure is an example of the commands to locate all the disk
drives that make up unit D104:
1. Enter the following command:
LOCATE D104
The LEDs on the disk drives that make up unit D104 will flash.
