6.2.1 Interpreting physical disk status
Physical disks resources can be mapped to logical volume groups, which are split
into Logical device ‘slices’ which are then shared as iSCSI or NAS. The number of
into Logical device ‘slices’ which are then shared as iSCSI or NAS. The number of
Physical disks may not necessarily correlate 1:1 with the hardware disk pool (e.g.
number of AMC drive carriers), because physical disks may include volumes created
through RAID services that mask the individual hardware disk members. From the
through RAID services that mask the individual hardware disk members. From the
ATCA-S201 perspective, physical disks are presented as Linux SCSI devices
(/dev/sd[a-z]).
