312 VM/HSC 6.0 System Programmer’s Guide
1st ed., 6/30/04 - 312579601
(addr0,...addr19)
specifies the device numbers for the panel. The numbers are from the top of the
panel down. If a device number is omitted, this means that the host cannot
access a drive in that particular position in the panel, or the drive does not exist.
Notes:
1. Blanks as well as commas may be used to separate the drive
specifications.
2. The total number of drives specified (including comma placeholders) must
be 4, 10, 16 (for an SL8500), or 20. You cannot specify 20-drive panels on
9740 (TimberWolf) LSMs or SL8500 libraries.
3. Before this utility can be executed, all cells in the panel must be empty if
the user is moving to or from a 20-drive panel configuration.
4. The user can change a drive panel between a 4- or 10-drive panel (normal)
and a 20-drive panel (wide) without running a reconfiguration. Affected
panels must be empty and no cells in the panels can be allocated to
cartridges.
To ensure that drive panels being changed from normal to wide
configurations (or vice versa) remain empty, freeze them with the SET
FREEZE utility. Then, move all cartridges to other panels or LSMs.
If a panel type is changed by SET SLIDRIVS, the new panel will not be
frozen. Frozen panels whose panel type did not change remain frozen after
SET SLIDRIVS.
5. HSC does not allow duplicate addresses for drives. If it becomes necessary
to exchange the drive addresses on one panel with the drive addresses on
another panel, the addresses on one of the panels must first be changed to
temporary addresses that are not currently defined. For example:
LSM0, PANEL10, ADDRESSES!400,401,402,403
LSM1, PANEL11, ADDRESSES!404,405,406,407
If the 400-403 addresses are to be moved to LSM1 and 404-407 are to be
moved to LSM0, the SET utility must first be run to change the LSM0
addresses (400-403) to 900-903 (or some other addresses that are not
currently defined). The SET utility is then run to change the LSM1
addresses to 400-403. The utility is run a third time to change the
temporary LSM0 addresses (900-903) to 404-407.
6. On all LSMs, drives are defined to the HSC from top to bottom, with
addr0 representing the topmost drive and addrn the bottommost drive.
However, on a 9740 10-drive panel LSM, the drives are populated and
configured to the 9740 LSM from bottom to top. (9740 4-drive panels are
configured to the 9740 LSM from top to bottom, as are all other LSM
drive panels.)
