Byte 00, Bits 5 through 0 - Page Code

The Page Code identifies the page being transferred. The valid value

is 10h (Device Configuration Page).

Byte 01 - Page Length

The Page Length indicates the number of bytes in the Device

Configuration Page that follow this byte. The valid value is 0Dh.

Byte 02, Bit 6 - CAP (Change Active Partition)

EXB-8505 If the loaded tape is formatted with two partitions (8500c format

only), you can use the CAP bit to move the tape from the current

partition to the other partition. You specify the new partition in the

Active Partition field (byte 03). Note that the EXB-8505 does not

actually move the tape until it receives a tape motion command such

as READ or WRITE. Values for the CAP bit are as follows:

0 – Do not move the tape from the current partition.

1 – Move the tape to the partition indicated by the Active Partition field.

If the CAP bit is set to 1 and the partition specified by the Active

Partition field is different from the currently active partition, the

EXB-8505 positions the tape to the logical beginning of the new

partition (LBOP) after receiving a tape motion command. If the CAP

bit is set to 1 and the partition specified by the Active Partition field is

the same as the currently active partition, the EXB-8505 does not

change the tape’s position. This is not an error.

Notes:

If the EXB-8505 is not ready when it receives a request to change

the active partition, it returns Check Condition status with the

sense key set to Not Ready (2h).

If the currently loaded tape does not contain two partitions, the

CAP bit must be 0.

In the MODE SENSE data, the value returned for this bit is always

0 (no change in position).

EXB-8205 The EXB-8205 does not support partitions. The valid value for this bit

is 0.
