Configuring Library Partitions
Example 6: four-partition library
Rail | Library E |
|
|
1 | Partition 1, Host A (ACSLS) |
2 | Partition 2, Host B (HSC) |
3 | Partition 3, Host C (HSC) |
4 | Partition 4, Host D (ACSLS) |
|
|
■Partition 1 is controlled by an ACSLS host.
■Partition 2 is controlled by an HSC host.
■Partition 3 is controlled by a second HSC host.
■Partition 4 is controlled by a second ASCLS host.
Defining Library Partitions
▼To Create Partitions
Note – It is recommended that you quiesce the library to all hosts before beginning this procedure. See the ACSLS and HSC documentation for details.
1.Select Tools > Partitions.
2.In the Partition ID column of the partition you want to create, select the rails that you want to include. For example, to include rails 1 and 2 in Partition 2 select Rail 1 and Rail 2 under the Partition ID 2 column.
Note – Partition IDs do not need to be contiguous. For example, you can create Partition 2 and Partition 4, with no Partition 1 or 3.
Note – Rails within a partition must be adjacent to one another. For example, you can create a partition that includes rails 3 and 4, or rails 2, 3, and 4, but not rails 2 and 4 only.
Note – Each rail corresponds to an LSM, with the ID of each offset by one. Rail 1 = LSM 0, Rail 2 = LSM 1, etc.
■Select Apply to apply the updates and continue to Step 3.
■Select Refresh to cancel the updates and restore the original screen settings.
3.A dialog displays, “This operation will take the library offline temporarily. Do you wish to continue?”
■Select OK to make the updates. The library goes offline and all host connections are dropped while the updates are made.
