SoftReboot White Paper (766152-001, March 2014)

1 Technologies/features

SoftReboot feature reduces the operating system reboot time experienced during routine system

maintenance. SoftReboot achieves this downtime reduction by skipping the platform hardware

reset and booting the next kernel directly from the current operating system instance.

The time saved due to SoftReboot solution varies across platforms and different hardware

configurations of the same platform. Hence, the down time savings due to SoftReboot are not

quantifiable.

SoftReboot integrated with DRD

With SRB feature, DRD can further reduce downtime during reboot process. SRB version

B.11.31.1303 supports DRD. DRD version A.3.12 supports SRB. For details about DRD, see

Dynamic Root Disk A.3.12.* Administrator's Guide at www.hp.com/go/drd-docs.

For proper functioning of this feature, the SRB version should be B.11.31.1303 or above and DRD

version should be A.3.12 or above.
