System boot and RAID controller failure
HPE StoreOnce 3100, 3520 and 3540 Systems boot from the p1224 RAID controller that is also connected to
the customer data storage disks.
HPE StoreOnce 5100 Systems boot from the onboard smart array controller which is connected to the two
OS disk drives in the rear of the server.
If a catastrophic failure of the boot RAID controller occurs, the system will not boot. This failure may only be
diagnosed from the server POST messages where the controller may report an error or a lockup code. In
these cases, contact HPE Support and provide information about the reported error code.
Other forms of noncatastrophic RAID controller failure will be reported in the Event Log and the Hardware
pages on the StoreOnce GUI.
