Guidelines
Essential elements for understanding partitions are:
•
Clear communication between all parties,
such as system
programmers, network administrators, both ACSLS and ELS/HSC
administrators, and service representatives.
•
Only a single library may be partitioned—pass-thru port (PTP) operations
are not allowed. However, if libraries are currently connected using PTPs,
and you—the customer—what to keep that structure for future
development; a service representative can disconnect the local network
interface and connections within the library to disable this configuration.
Y
ou will not need to disassemble the complex.
•
Customers must be current on maintenance levels of their library
management software (ACSLS and ELS/HSC).
See the software and firmware requirements on
page 206
.
•
Depending on the library configuration, each rail has:
-
Minimum capacity of
362
cartridges
1
.
-
Maximum capacity of 2,522 cartridges
2
.
-
From 1 to 16 tape drives.
•
Each rail is the smallest element of a partition, but partitions may include
more than one rail. If a partition includes more than one rail, those rails
must be
adjacent
.
•
Hosts with a common database—ELS/HSC hosts using a common Control
Data Set (CDS)—can share a partition; these hosts are called a “host
group.”
A single ELS/HSC CDS cannot connect to more than one partition within
the same SL8500 library; however, you can have one partition from each
library in the same CDS. If you have two partitions in a library, you must
also have two CDS; three partitions, three CDS.
•
When partitioned, the library controller reports rails assigned to another
partition within the library as “unallocated” (ELS/HSC) or as a new
“SL8500_Unalloc LSM” (ACSLS). This provides two things:
-
It displays the entire library, and
-
If partitioning is changed (rails added to or removed from a partition),
cartridge locations remain constant.
1.
The basic configuration of an SL8500 library is 1,448 cartridges; spread across four
LSMs provides 362 cartridges per rail.
2.
The maximum configuration of an SL8500 library is 10,088 cartridges; spread across
four LSMs provides 2,522 cartridges per rail.
