Expading VD size

[rui.cruz]

Hello all,

I am having an issue where i have a RAID 5 with 3x 480GB SSD, and i have replaced, one at a time, all the SSDs for 512GB ones with more performance.

Now the drives have all rebuilt without any issue and the VD is now good again, but i am unable to increase the size of the VD since the options appeared greyd out.

I have attached an image showing the size of the VD.

Is there any command or any way of increasing the VD size without adding more drives ? I have managed to do this with other brands, just wanted to know if its also possible with Cisco devices.

Thank you all for the help.

Best regards,

Rui Cruz

Assuming this is an LSI/AVAGO/BROADCOM raid controller, you might take a look at getting storcli utility installed.

https://docs.broadcom.com/doc/MR-TM-StorCLI-UG

storcli /cx/vx expand size=<value> [expandarray]
storcli /cx/vx|vall show expansion

If you go into the F2/bios type setup menu, I believe there might still be an option called "HII Configuration Utility" (or Avago/Broadcom Megaraid config Utility)  that will launch a UEFI menu config utility that might allow you to do similar config changes.

I have used that before to expand raid volumes by adding additional disks. (https://community.cisco.com/t5/data-center-and-cloud-documents/expanding-virtual-drive-on-12gb-sas-controller-by-adding/ta-p/3164586)

Hello Kirk,

Thank you for your reply.

I have managed to increase the size of a virtual disk by adding more drives. But in this situation i haven't added more drives, I replaced the ones existing with better ones, and I am trying to use the extra space the drives provide to increase slightly the VD size.

 The controller i have is a Cisco 12G SAS Modular Raid Controller for C460 (03:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3108 [Invader] (rev 02)).

I will follow your suggestion and try using the StorCli to see if i can upgrade the VD size.

Once again thank you, and I will give some fedback with the results.

Best regards,

Hello Kirk,

Just to let you know I was able to increase the size of VD.

I installed storcli just as you suggested and ran the commands you gave. Worked like a charm.

Thank you very much for your help.
