HP 6Gb SAS BL Switch for HP BladeSystem c-Class Replacement Instructions

Installing the replacement switch
Before installing the replacement switch, note the
following:
• The SAS BL Switch may be hot-installed in an
operational c-Class enclosure.
• The SAS BL Switch does not have a power on/off
button. Power is automatically applied when the
switch is installed in the enclosure.
• Re-connect SAS cables to the external storage
enclosures only after confirming that the desired
firmware version is installed on the switch.
1. Prepare the switch.
2. Install the switch in the open interconnect bay.
When installed in an operational enclosure, the
switch automatically powers up and performs a
series of Power On Self Tests.
IMPORTANT: Do not connect SAS cables
to external storage enclosures until you have
accessed the switch and confirmed that the
desired firmware version is installed on the
switch. (See “Updating switch firmware”
(page 2)).
3. Note the following during startup:
• All eight Link LEDs will blink while the switch
and the VSM software are starting up.
• Startup time might be as long as five minutes.
If startup is longer than five minutes, confirm
that a supported version of Onboard
Administrator is installed on the system.
• After the switch and the VSM software has
started up successfully, the Health LED will be
solid green.
• If the Health LED is amber or off, remove the
switch from the BladeSystem Interconnect Bay
and reinstall it, pressing firmly on the switch
and its locking latch handle to ensure it is
seated properly. If trouble persists, see the
"Troubleshooting" section of the HP
BladeSystem enclosure setup and installation
guide.
For more information about switch LED patterns,
see “Verifying component failure” (page 1).
Verifying proper operation
Check the following to verify that the switch is working
properly:
• Switch LEDs—See “Verifying component failure”
(page 1) and check for healthy LED patterns.
• Onboard Administrator—View system information
and confirm that the device status is Normal. For
more information, see the Onboard Administrator
user guide, available on the BladeSystem manuals
page http://www.hp.com/support/manuals.
• Virtual SAS Manager—View Status Alerts and
device information for messages regarding the
replacement.
Updating switch firmware
Firmware on the replacement switch may be a different
version than that on the failed switch. Before operating
or connecting cables to the replacement switch, make
sure that it is running the desired version. In addition,
when two 6Gb SAS BL Switches are installed in the same
row of a BladeSystem enclosure, make sure that both
are running the same firmware version.
The currently-installed firmware version is displayed in
the VSM near the center of the Virtual SAS Manager
banner. Access the VSM and make note of the installed
firmware version on each 6Gb SAS BL Switch.
If needed, update firmware on the switches. For
information, see the HP 6G Virtual SAS Manager User
Guide.
Cabling the switch
Re-connect the SAS cables to the replacement switch,
making sure to connect each cable to its designated
port.
IMPORTANT: Confirm that firmware installed
on the external devices is supported for use with
the firmware installed on the switch. Consult the
QuickSpecs for the switch and all attached
external devices and confirm that compatible,
supported versions of firmware are installed.
Configuring the switch
In dual-domain switch deployments, configuration
settings automatically replicate from the active switch to
the replacement switch. Access the VSM and view the
configuration information for each switch to confirm.
Replacement procedures are now complete; no other
steps are necessary. Proceed to “Returning the failed
component” (page 2).
In single-domain switch deployments, restore
configuration settings as appropriate to your
environment:
If the switch configuration was captured to a file prior
to the replacement, do the following to restore that
configuration onto the replacement switch:
1. Use a secure copy tool such as pscp for Windows
or scp for Linux as follows to copy the file to the
/var/image directory on the switch:
Example pscp (Windows) command:
pscp.exe -scp -l Administrator -pw
Password
config.txt 10.10.10.10:/var/image
Example scp (Linux) command:
scp /home/userXXX/config.txt
Administrator@10.10.10.10:/var/image/.
2. Access the VSM CLI for the replacement switch.
3. Enter the input command as follows to restore the
saved configuration on to the replacement switch:
sw loc=local input file=config.txt
(Where sw loc=local represents the switch and
config.txt represents the name of the
configuration file.)
Additional input methods and options are available.
For more information about accessing the CLI and using
these commands, or for information about using the GUI
to perform these tasks, see the HP 6G Virtual SAS
Manager User Guide.
If the switch configuration was not captured electronically
prior to the replacement, access the VSM GUI or CLI
and manually re-enter all configuration settings.
Key configuration steps include:
• Entering switch parameters.
• Creating zone groups.
• Assigning zone groups to enclosure blade ports
(servers).
For more information about using the VSM GUI or VSM
CLI to perform these configuration tasks, see the HP 6G
Virtual SAS Manager User Guide.
