Drive table (DRIVE)

The drive table contains one row for each optical drive, whether operator-accessible or library-resident. The DB2 name of the drive table is DRIVE. The table is defined in table space OCDRVTSP. Table 1 describes the attributes of the columns in the drive table. A row is inserted into the drive table the first time that an optical disk drive with a given name is defined using the ISMF Library Management application.

Note: ** No longer used.

The NAME column has a unique index. Therefore, each optical disk drive defined in the drive table must have a unique name.

The combination of CTC, SCSI, and LUN must be unique for each optical drive defined in the drive table, because there is a partitioned index on the CTC, SCSI, and LUN columns. CTC, SCSI, and LUN constitute the device address of the optical disk drive. This address is used by OAM to address the optical drive during I/O operations.

The online status, operational status, drive type, and device type columns in the drive table require specific values:

ONLINE

Indicates whether the optical drive is online or offline to a particular system.

Y: The optical drive is online to a specific system.
N: The optical drive is offline to a specific system.

OPERATNL

Indicates the operational status of the optical drive.

Y: Optical drive is operational.
N: Optical drive is not operational.

DRIVTYPE

Indicates the type of optical drive.

L: Optical drive is in a library.
S: Optical drive is a operator-accessible (stand-alone).

DEVTYPE

Indicates the device type of the optical disk drive.

3995-131: This device is a 3995 Model 131.
3995-132: This device is a 3995 Model 132.
3995-133: This device is a 3995 Model 133.
3995SW3: This device is a 3995 Model SW3.
3995SW4: This device is a 3995 Model SW4.

MEMBER

The instance of OAM, to which the drive is online, that is managing the optical drive within the Parallel Sysplex.
