Replacement Instructions

Abstract

This document details procedures for replacing a failed HP

3Gb SAS BL Switch in an HP BladeSystem c-Class enclosure.

*496787-003*

HP Part Number: 496787-003

Published: October 2012

Edition: 3

Observe the following:

CAUTION:

• All enclosure bays must be populated with a

module or blanking panel for the enclosure

to cool properly. Remove a module or

blanking panel from an enclosure bay only

when a new module is available to install in

that bay.

• Parts can be damaged by electrostatic

discharge. Use proper anti-static protection.

For more information, see HP c-Class

BladeSystem or SAS BL Switch user guides.

Capturing existing configuration settings

If possible, capture an electronic copy of the existing

switch configuration, which can later be restored onto

the replacement switch. In single-domain switch

deployments, if the switch configuration cannot be

captured electronically, record the settings manually and

then manually re-enter them on the replacement switch.

To back up the existing switch configuration

electronically:

1. Access the VSM Command Line Interface (CLI) on

the switch.

2. Enter the capture command as follows to save

the configuration to a temporary location on the

switch:

switch local capture file=/var/tmp/config.txt

(Where switch local represents the switch and

config.txt represents the name of the

configuration file. By default, the configuration file

is saved in the /var/tmp directory on the switch.)

3. Use a secure copy tool such as pscp for Windows

or scp for Linux as follows to copy the file from the

switch to a different location:

Example pscp (Windows) command:

pscp.exe -scp -l Administrator -pw

Password

10.10.10.10:/var/tmp/config.txt c:\backup

Example scp (Linux) command:

scp

Administrator@10.10.10.10:/var/tmp/config.txt

/home/userXXX/.

Additional capture 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.

Verifying component failure

Before replacing the switch, check the following and

confirm with HP support that it has failed:

• Onboard Administrator—View system and device

status displays for Critical, Major, Minor, and

Warning icons. For more information, see the HP

BladeSystem Onboard Administrator User Guide.

• Switch LEDs—View the Health, Link, and Fault LEDs

for error patterns.

Removing the failed switch

Before removing the failed switch, observe the following:

IMPORTANT:

• Server blades with access to the switch must

be offline during these replacement

procedures.

• The switch must be powered off through

Onboard Administrator before disconnecting

the SAS cables. Failure to power off the

switch before disconnecting the SAS cables

may cause the replacement switch to be

unresponsive.

1. Power down all servers with access to the switch.

2. In Onboard Administrator, power off the switch.

• In the OA GUI: Select the Virtual Buttons tab

for the switch, and then click Power Off the

switch.

• In the OA CLI: Enter the following command:

poweroff interconnect xxx, where xxx

is the switch interconnect bay number.

3. Disconnect all cables from the failed switch, making

sure to label each cable with its port number to

facilitate re-connection.

4. Remove the failed switch from the enclosure

interconnect bay.

3. Installing the replacement switch Before installing the replacement switch, note the following: • • • 1. 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. The SAS BL Switch may be hot-installed in an operational c-Class enclosure.
