Notes:
1. In the preceding table, x is equal to the rack number and y is equal to the I/O subsystem position in
the rack. The SCSI ID for each drive is set when the drive is installed. Each I/O subsystem can have
up to four DASD 4-packs installed. The SCSI IDs for the drives in each 4-pack are 8, 9, a, and b, from
left to right.
2. The DASD attachment locations are as follows:
v DASD 1, 2, 3, 4 are attached to Ux.y-P3 DASD backplane.
v DASD 5, 6, 7, 8 are attached to Ux.y-P4 DASD backplane.
v DASD 9, 10, 11, 12 are attached to Ux.y-P5 DASD backplane.
v DASD 13, 14, 15, 16 are attached to Ux.y-P6 DASD backplane.
