Verifying Component Failure - HP StorageWorks 9100 - Extreme Data Storage System Instructions

Verifying component failure

Before replacing a 3Gb SAS 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 Onboard Administrator user guide.
• Switch LEDs—View the Health, Link, and Fault LEDs for error patterns.
1 Unit ID LED
2 Health LED
3 Release button for the locking latch handle.
4 Link LED
5 Fault LED
6 SAS ports (to external storage)
• Off—Normal
• Solid blue—Being identified
• Blinking blue—Firmware is being up-
dated
• Off—Not powered up
• Solid green—Healthy
• Blinking amber—Error, there is a
problem with the switch
• Off—No link between the server and
storage
• Solid green—Link between server and
storage is established
• Blinking green—Activity on the estab-
lished link
• Off—Normal
• Amber—Link error, there is a problem
with the port
Removing the failed switch
NOTE:
• In redundant-switch environments, the 3Gb SAS Switch may
be hot-replaced in an operational enclosure.
• In single-switch environments, all activity through the switch
must be halted prior to the replacement.
• The 3Gb SAS Switch does not have a power on/off button.
Power is automatically applied or removed when the switch
is installed or removed from the enclosure. Alternatively, power
can be applied or removed through the Onboard Administrator
application.
For illustration purposes, the following images demonstrate removing a
3Gb SAS BL Switch in interconnect bay 5 of a BladeSystem c7000
enclosure.
1.
Stop all traffic through the failed or failing switch.
2. Use Onboard Administrator to shut down the switch. (Optional, but
a best practice.)
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.
