Synchronizing RAID After Installing a Second Cisco FlexFlash Drive
After you install or replace a second Cisco FlexFlash drive, you must synchronize the RAID partition
by using the Cisco UCS Server Configuration Utility (SCU).
The SCU provides an option to synchronize the Hypervisor VD, configured as a RAID-1 disk. This
feature is available only when both Cisco FlexFlash drive slots are populated.
When one member slot of the SD card is corrupt, use this option to synchronize the hypervisor data
across two members of the RAID-1 virtual disk. You can initiate this synchronization only if two cards
are detected and the RAID-1 group is determined as unhealthy (one member is corrupt).
Step 1
Click the
Hypervisor Sync
icon on the toolbar of the SCU interface.
A dialog prompts you to confirm that you want to synchronize the Hypervisor RAID.
Step 2
Click
Yes
.
A dialog is displayed when the synchronization is complete.
Step 3
Click
OK
.
After you click OK, the Hypervisor Sync icon on the toolbar is greyed out.
For more information about the utility, see the
Cisco UCS Server Configuration Utility User Guide
.
