IBM TotalStorage 3494 Tape Library, Operator'S Manual

Page: 170 / 605

While in the Online state, the Library Manager is capable of receiving, queueing,
and executing commands from attached hosts.
Whenever the Library Manager is brought online, it checks for “Fast Ready”
categories. If the 3494 Tape Library has a VTS installed and there are no “Fast
Ready” categories defined, a warning message is displayed (see Figure 64). The
message simply warns that at least one “Fast Ready” category should be defined.
If you do not select the OK push button, the warning message is removed
automatically after one minute. If a VTS is not installed or there are “Fast Ready”
categories defined, no warning message is displayed. See “Set VTS/VE Category
Attributes” on page 243 for information on setting “Fast Ready” categories.
Note:
If you see this message, notify your system administrator.
Offline
Select the Offline... option for the cartridge accessor to complete all queued
requests. No additional requests are accepted. During the processing of queued
requests, the 3494 Tape Library is in the Offline Pending state. If you select the
Offline... option and the Library Manager is already offline, your selection is
ignored. No messages are sent to the attached control units. The window indicates
Offline Pending while the Library Manager is in the process of going offline.
You are prompted to confirm your selection. The icon preceding the Offline...
option indicates that you selected the Offline state.
