IMPORTANT:
with a pair of network switches. If not using a bonded network, clients should be disconnected
before starting the procedure. In addition, both externally facing uplinks must be connected to the
external network of your volumes. If uplinks are not connected to the external network, connectivity
will be lost when one of the Flex- 1 0 or FlexFabric switches goes offline during a firmware update.
To replace a VC Flex- 1 0 or VC FlexFabric module:
1.
Disconnect the network connections into the VC Flex- 1 0 or VC FlexFabric module (bay 1 or
2).
2.
Remove the VC Flex- 1 0 or VC FlexFabric module.
3.
Replace the VC Flex- 1 0 or VC FlexFabric module.
4.
Reconnect the cables that were disconnected in Step 1 to their original ports.

Replacing the SAS switch
This section provides instructions for removing and replacing the HP 6Gb SAS BL switch in the HP
4630 system.
IMPORTANT:
This causes storage access to set a preference to all LUNs in the remaining data path. This preference
remains in place until the controllers in the blade enclosure are power cycled, or the remaining
path becomes unavailable.
To replace the SAS switch:
1.
Log in to the Onboard Administrator and identify the SAS switch that has failed.
2.
Power down the storage blades.
3.
Power down the SAS switch from the Onboard Administrator.
NOTE:
Resetting or toggling the power state of the interconnect could
result in an interruption of I/O. Are you sure?
Select OK to continue.
4.
Power down the disk enclosures.
5.
Disconnect all SAS cables from the switch; note which cable goes to which port.
6.
Remove the failed switch from the blade enclosure chassis.
7.
Install the replacement switch in the same slot in the blade enclosure chassis.
Once installed, the SAS switch powers on automatically.
8.
In the Systems and Devices section of the HP Virtual SAS Manager, it may indicate a firmware
mismatch ("Mismatch" displays next to the SAS switch). Select Update SAS Switch Firmware
to display version information. If the versions that display are the same, no upgrade is needed;
continue with step 10. If the versions do not match, continue with upgrading the switch
firmware.
NOTE:
IMPORTANT:
update is complete.
Clients will lose connectivity during this procedure unless using a bonded network

If a SAS switch fails, storage access continues through the remaining SAS switch.
When a switch is powered down, the following message displays:
If the versions do not match, the Force VSM Active option will be unavailable.
Do not attach the SAS cables to the replacement switch until the firmware
