Multiple Library Stacks
Multiple Library Stack
Requirements
0
To ensure the proper operation of your multiple library stack, review the following list of
multiple library stack requirements:
• Multiple library stacks that contain a Scalar 50 can NOT exceed two library cabinets.
• The Scalar 50 must be the Master library in a multiple library stack containing PX502
libraries.
• The Master library must always be in the bottom most position in the library stack.
• If a Scalar 50 is stacked with PX502 libraries, the PX502 can NOT contain an HP LTO-
2 tape drive or a FC1202 Fibre Channel bridge. These devices are not supported by
Scalar 50.
• All Scalar 50 libraries must have full capacity enabled.
• A library that contains SAS drives cannot be shared with SCSI or Fibre Channel
libraries.
• If your Scalar 50 is not already enabled with full slot capacity, you must initially
configure the Scalar 50 libraries and enable
Full
capacity with a
Capacity Key
before
configuring the cabinets as Master and Slave libraries (see the
Scalar 50 User’s Guide
PN 81-81768 located on the documentation CD for more
Capacity Key
information).
Preparing the Library for a
Multiple Library Stack
0
If the library will be installed in a rack with other Scalar 50 or PX502 libraries, you must
prepare each chassis prior to installation. Preparing the library chassis for installation into
a multiple library stack consists of:
• Removing the FlexLink cover plates
• Installing the alignment hardware
To prepare the library chassis for multiple stack operation:
1
Remove two Phillips screws securing each FlexLink cover located on the top and
bottom of the library using a #1 Phillips screwdriver (see
figure 37
).
Note:
If the library is NOT being installed with other libraries to operate in a multiple
library stack, it is not necessary to complete the following instructions.
Note:
Remove the bottom FlexLink cover on every library except the bottom
library in the stack. Remove the top FlexLink cover on the bottom library in
the stack.
