HSD10 Command Utility Maintenance Operations
The HSD10 Command Utility provides a means of setting and displaying operational
parameters. It also provides commands to qualify, format, and exercise attached SCSI
devices directly from the HSD10. Procedures to use these maintenance commands are
described in this section.
Devices are referenced at the HSD10 level by physical device names (using templates D1il
and T1il). These names are used with device commands described in this section. Do not
confuse these with the "mapped" MSCP/TMSCP names the HSD10 presents to the host
systems.
Formatting and Qualifying a SCSI Drive
You can format a specified device that is AVAILABLE to the HSD10 adapter using the
FORMAT command. After the format operation is completed, you should use the
QUALIFY command to verify that the device is ready for use. You should also run the
DISKTEST procedure given in Section Table 4-5 and the StorageWorks Solutions HSD10
Array Controller User’s Guide, EK-HSD10-UG, to further test the drive before it is
returned to service.
Format and Qualify Task Procedure
Use the following procedure to format and qualify a specified device:
1. At the node name prompt, enter the SHOW UNIT command to determine device
status.
2. If the device status is not AVAILABLE, enter the appropriate operating system
commands (DISMOUNT, for example) to make the device available to the HSD10
adapter.
3. At the node name prompt, enter the SELECT command and specify a physical device
name.
