Minimum Disk-Drive Configuration
Minimum Disk-Drive Configuration
A system must include a minimum of four internal disk drives, all having the same
product number. This table lists the factory-default device name, location, and purpose
of each of these four internal disk drives.
Locations of $DSMSCM and $AUDIT as Mirrored Volumes
HP recommends that you configure $DSMSCM and $AUDIT as mirrored volumes. This
table lists the locations of $DSMSCM and $AUDIT if they are configured as mirrored
volumes.
Other Internal Disk Drives
Any other internal disk drives that are ordered are also configured and named at the
factory. To determine the factory-default configuration of a systems’s internal disk
drives, after you install and start your system, use SCF to determine the system
configuration. Refer to the SCF Reference Manual for G-Series RVUs for more
information about this task.
The two physical disk drives of a mirrored volume must have the same product number
(except during an online upgrade).
