My blade 7226T-T2 is not able to boot up all the HDDs. The server became unresponsive. Console showed numerous IO errors on /dev/sda. System would not boot after being reset and BIOS shows no disk device attached to the node.
All our Super blades only work with Enterprise HDDs. Please double check again to make sure all your HDDs are Enterprise HDDs. You may check our Tested HDDs from the SBI-7226T-T2 link below to verify.
