9. When the upgrade is complete, select Reset Hardware to activate the new firmware on the
replacement switch.
10. In the HP Virtual SAS Manager, select Force VSM Active.
NOTE: This selection copies the zone and firmware information from the active switch to
the passive, replacement switch. The replacement switch then becomes the active switch.
11. Reconnect the SAS cables to their original locations; see “HP 4630 system cabling” (page 35).
12. Power on the disk enclosures.
Using the HP Virtual SAS Manager, verify the status of each disk enclosure and the zone
status. Ensure that the HP Virtual SAS Manager is not reporting any warnings or errors.
13. Power on the storage blades.
NOTE: The SAS switch should now provide a redundant access path to storage. Storage controllers
will distribute I/O evenly over the switches upon restart.
Replacing a SAS cable

Select storage system in the management group and select either the Power off or Reboot
option to shut down the storage blade.

See “HP 4630 system cabling” (page 35) for an illustration of HP 4630 system connectivity.
Replacing the disk enclosure I/O module
This section describes how to remove and replace the disk enclosure I/O module on the D2700

enclosure containing the failed I/O module. Then, power down the storage blade using the
CMC. Select storage system in the management group and select either the Power off or
Reboot option to shut down the storage blade.
• Power down the disk enclosure before disconnecting a SAS cable.
