Cisco UCS Flexflash configuration…
Issue:
I’d like to take advantage of RAID 1 on for an ESXi install on Cisco UCS M4/5 Blades.
You’ll need the SD Module in your server for this.
Resolution:
Like all UCS configuration, its a policy and it’s a bit more of an art to deploy than most of the UCS policies. (See troubleshooting as you’ll likely need to follow those steps)
- Navigate to the Storage tab on UCS Manager > Select Create new policy > disk group policy under storage tab – define RAID 1 (Mirror)
- Additional configuration is required, turn off under the ServersĀ tab > Policies > Sub Org > “Your Name” > Local Disk Configuration Policy > esxi_sd_raid > MODE: “No local storage” <– this is set as the raid is handled in the flexflash config
- Once built, assuming your on a greenfield/test environment you will want to > Disassociate service profiles > Server Maintenance > reacknowldge….
- Wait to finish and re-associate the service template (assuming your using update profiles)
Troubleshooting:
You’ll find deploying ESXi may find the storage isn’t compatible or throwing out an error, to resolve:
- Reset the FlexFlash Controller
- Format the Controller
- Assign 1 as auto sync
