5 Firmware
Firmware is managed using the Virtual SAS Manager (VSM) application. For more information, see
the HP Virtual SAS Manager user guide, available on the 3Gb SAS BL Switch page of the HP Manuals
website
.
As part of a routine system maintenance program, periodically check firmware versions installed on
system devices. Updates may include additional features and functions, performance enhancements,
support for newly released hardware, or fixes to known issues.
Firmware is pre-installed on each switch in the factory, but updated, alternative, or a preferred version
may be available. The following types of firmware are available for the 3Gb SAS BL Switch; choose
the firmware type that is best for your environment:
•
Firmware versions earlier than 2.0.0.0—Single zone support. This firmware version supports
connections only to shared SAS storage enclosures such as the MSA2000sa and tape devices
such as the MSL G3 tape libraries. All server blade bays have access to all storage enclosures
connected to the switch. These settings are pre-configured and cannot be altered. To restrict access
to the storage, use features provided with your storage management software.
•
Firmware versions 2.0.0.0 and later—Multi-zone support. Supported for use with shared SAS
storage enclosures such as the MSA2000sa, tape devices such as the MSL G3 tape libraries, and
zoned SAS storage enclosures such as the MDS600. Server bays access the storage enclosures
through zone groups created in the Virtual SAS Manager (VSM) application embedded in the
switch firmware. The zone groups provides user-defined assignment of server bays to one or more
desired zone groups.
The installed firmware version is displayed in the VSM near the center of the HP Virtual SAS Manager
banner. Access the VSM and note the installed firmware version on each 3Gb SAS BL Switch.
IMPORTANT:
•
When two 3Gb SAS BL Switches are installed in the same row of an enclosure, make sure that
they are running the same firmware version.
•
Before updating switch firmware, HP strongly recommends backing up the configuration to an
FTP server for safekeeping. For more information, see the
HP Virtual SAS Manager user guide,
available on the 3Gb SAS BL Switch page of the HP Manuals website
