Important tips

Connectivity differs depending on the firmware version installed on the HP 3Gb SAS BL Switch:
◦ Firmware versions earlier than 2.0.0: All servers containing a P700m Controller are
automatically connected to all tape libraries. This is not configurable.
Firmware versions 2.0.0 or later: Switch-port zone groups must be created and assigned
◦
to server bays to grant access to the tape library.
For more information about configuration guidelines, see the EBS Design Guide.
SAS tape libraries must be connected to a port on an HP 3Gb SAS BL Switch (they cannot be
connected to a SAS port on an MSA or MDS storage enclosure).
Each SAS tape drive has a single SAS port. Redundancy is not supported, so the host end of
the fanout cable will be connected to only one port on one HP 3Gb SAS BL Switch. Either HP
3Gb SAS BL Switch in the BladeSystem c-Class enclosure may be used. The corresponding
switch port on the other HP 3Gb SAS BL Switch may be left open or connected to other tape
devices.
To use all four channels of the HP 3Gb SAS BL Switch port, use a SAS fanout cable, which
has one mini-SAS connector on the switch end and four mini-SAS connectors on the tape drive
end.
The available SAS fanout cables approved for use with the tape library or autoloader and
the HP 3Gb SAS BL Switch include:
AN975A – 2m External Mini-SAS to 4X1 Mini-SAS Cable Kit
◦
AN976A – 4m External Mini-SAS to 4X1 Mini-SAS Cable Kit
