Manage Logical Volumes; Maximum Number Of Logical Volumes For Base (Non-Ptp) Vtss; Maximum Number Of Logical Volumes For Ptp Vtss - IBM TotalStorage 3494 Tape Library Operator's Manual

Manage Logical Volumes

Notes:
v This feature is not available for the TS7700 Virtualization Engine.
v You can view the Manage Logical Volumes window from the Specialist
(see "Specialist Features and Functions" on page 396)
v In a PtP VTS configuration, the insertion of logical volumes is controlled
only from the User Interface distributed library.
The Manage Logical Volumes window (Figure 176 on page 281) allows two
operations — the insertion of logical volumes into a VTS and/or changing the
construct names of existing logical volumes. The maximum number of logical
volumes that can be inserted depends on library configuration. See Table 14 and
Table 15.

Volume Expansion
3494 B20 VTS with five installations of FC
4036, Logical Volume Expansion (see 279)
Note: Each increment of FC 4036 increases the number of available logical volumes
by 50,000 to the maximums listed in Table 14 and Table 15.
Volsers must be six characters in length and must be unique within a physical
library. A logical volume's volser cannot match another logical or physical
volume's volser. If a duplicate volser is encountered, the duplicate is not inserted.
To insert logical volumes, perform the following steps:
1. Select the Insert new logical volumes radio button.
2. Enter a volser or range of volsers to be inserted into the 3494 Tape Library.
3. Select the cartridge type to be emulated.
4. Select management constructs in the drop-down lists beneath Storage Group,
Storage Class, Management Class, and Data Class. Select Default or one of the
existing constructs. For MVS attached systems, select Default for all four
constructs.
