Altering Open SCSI Attribute Values
The “ALTER SCSI Command” (page 237) alters the attributes of an Open SCSI device in the system
configuration database. For a description of alterable Open SCSI attributes, see “ALTER SCSI
Attributes” (page 238).
Considerations for ALTER SCSI
• The process must be in the STOPPED state or not running before you can change its
configuration.
• Changes take effect when you restart the process.
• Verify the SCSI ID of the device is the same as the configured SCSIID value.
• Changing the Values of the Attributes for an Open SCSI Device
1. Stop the device:
-> STOP $S11500
2. Verify the device is in the STOPPED state:
-> STATUS $S11500
3. Change one or more attributes. For example:
-> ALTER $S11500, STARTSTATE STOPPED
4. Verify the change took place:
-> INFO $S11500, DETAIL
5. Start the device:
-> START $S11500
When the START SCSI command finishes successfully, the device is left in the STARTED state.
Deleting an Open SCSI Device
The “DELETE SCSI Command” (page 252) removes an Open SCSI device from the system
configuration database:
1. Stop the device:
-> STOP $S11500
2. Verify the device is in the STOPPED state:
-> STATUS $S11500
3. Remove the device from the system configuration database:
-> DELETE $S11500
4. Verify the device is removed from the system configuration database:
-> INFO $S11500
Managing an Open SCSI Device
Resetting an Open SCSI Device
The “RESET SCSI Command” (page 272) puts an Open SCSI device into the STOPPED state, substate
DOWN, reading for restarting:
1. Check the current status of the Open SCSI device:
-> STATUS $S11500
2. If it is not in the STOPPED state, substate DOWN:
-> RESET $S11500
