HP 3Gb 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 3Gb 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 3Gb SAS BL Switch.
If needed, update firmware on the switches. For
information, see the HP 3G Virtual SAS Manager User
Guide.
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 less than 2.0.0.0—Single open
zone support.
nl
By default, all blade servers have access to all
storage connected to the switch. These settings are
pre-configured and cannot be altered. To restrict
access to the storage, use features included in your
storage management software.
• Firmware versions 2.0.0.0 and higher—Multi-zone
support.
nl
By default, for servers to access storage, switch-port
or drive-bay zone groups must be created. Zone
groups provide user-defined isolation within the
switch.
IMPORTANT: When moving from single open
zone firmware to multi-zone firmware, you must
configure zone groups and assign them to the
servers. Otherwise, the servers will not be able to
access the storage. (See “Configuring the switch”
(page 2).)
Cabling the switch
Re-connect the SAS cables to the replacement switch,
making sure to connect each cable to its designated
port.
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/tmp directory on the switch:
Example pscp (Windows) command:
pscp.exe -scp -l Administrator -pw Password
c:\backup\config.txt 10.10.10.10:/var/tmp/.
Example scp (Linux) command:
scp /home/userXXX/config.txt
Administrator@10.10.10.10:/var/tmp/.
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 local input file=/var/tmp/config.txt
(Where sw 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, see the HP 3G Virtual SAS Manager
User Guide.
If the switch configuration was not captured electronically
prior to the replacement or, if during the replacement
you upgrade from single open zone firmware to
multi-zone firmware, access the VSM GUI or CLI and
manually re-enter all configuration settings.
For more information about using the VSM GUI or VSM
CLI to perform these configuration tasks, see the HP 3G
Virtual SAS Manager User Guide.
Returning the failed component
Follow instructions shipped with the replacement part.
