HP StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries User and Service Guide (AK378-96059, December 2012)

Figure 102 Mailslot-capable magazine and slot, each marked with a white dot
The library will eject the mailslot in the lower left magazine when instructed to open mailslots. After
the mailslot is closed, the library will inventory the tapes in the mailslot, but not the rest of the tapes
in the magazine, which allows the library to resume operations sooner.
On the MSL8096, the upper-right magazine can be configured as a 12–slot mailslot. All of the
right-side magazines are the same so it does not have a special marking. When instructed to open
both mailslots, the library first ejects the lower-left mailslot and then unlocks the upper-right mailslot
a few seconds later. The library does not eject the upper-right mailslot. The upper-right mailslot
remains unlocked until 30 seconds after the lower-left mailslot is replaced. After the upper-right
mailslot is replaced, the library inventories all of the tapes in the magazine. The OCP displays a
series of informative messages so you can see what the library is doing.
NOTE: If you exchange the magazine in the lower-left position with one that has different mailslot
capabilities, the library displays a warning that the mailslot type is incompatible with the
configuration.
To access the mailslots:
1. Highlight Operations -> Open Mailslots and press OK to select it.

2. On the MSL8096, if both mailslots are enabled, select which mailslots to open. The menu will
cycle through Bottom Left (3), Both (15), or Top Right (12).
3. The mailslot located in the lower left magazine ejects automatically. Pull the magazine out
until you can access the tape cartridge (see Figure 104 (page 129)).
