Cisco Security MARS 110 error - sfdisk:Cannot open /dev/sda for reading

HI when installing the MARS ver 6.0.1 we are getting this error sfdisk:Cannot open /dev/sda for reading, but found that this a bug for that ver BUG id : CSCso92379 - Cannot open /dev/sda for reading" error seen on installing Gen1 GC

So we tried installing the ver 5.3 now also getting the same error, pls let me know is this a hardware issue or a bug

It sounds like there may either be a problem with the RAID controller [configuration] or, though unlikely a hardware failure. You'd need to check the RAID controller BIOS to see if there's a hard disk drive problem or RAID configuration problem. Also check RAID controller is damaged as disks are not recognized at all.

Rebuild the Raid and reimage the appliances.
