Resuming Operations

The following procedure resumes operations on a replacement tape drive. The

procedure uses an example drive named $TAPE1.

5 If the SCSI port on the PMF CRU, IOMF CRU, or ServerNet/DA is not

configured for a tape drive or if the replacement drive has a different model

number than the previous drive, delete the previous drive and add the new

drive using SCF. Deleting and adding the drive causes the system to size

the new drive and enter the appropriate data into the system configuration

database.

6 Using OSM, TSM, or SCF, verify that the SCSI port is configured to support

the tape drive.

7 Using OSM,TSM, or SCF, place the tape drive in a STARTED state.

8 If the drive starts successfully, exit OSM, TSM or SCF. If the drive does not

start successfully, reset the drive using SCF and try again. If the drive still

does not start, check the EMS event log, determine why the problem

occurred, and resolve the problem.

Note: The drive cannot be reset using OSM or TSM. The SCF Reset

Tape command is part of the RESET SCSI command. It puts a tape drive

into the stopped state, substate DOWN, ready for restarting.

9 Restart any application software that was using the tape drive.

For general information about using SCF to manage tape devices, see the SCF

Reference Manual for the Storage Subsystem.
