HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX
Note 1:
The availability of a disk type depends on the disk array.
Note 2:
The devices are defined to the host as SCSI disk devices, even though the
interface is Fibre Channel.
Note 3:
The device capacity can sometimes be changed by the BIOS or host adapter
board. This may make actual capacity different from that listed in the table.
Note 4:
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders)
× (# of heads) × (# of sectors per track)
Example 1: For an OPEN-3 CVS volume with capacity = 37 MB:
# of blocks = (53 cylinders–see Note 5)
× (15 heads) × (96 sectors per
track) = 76320
Example 2: For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks = (53 cylinders–see Note 5)
× (15 heads) × (128 sectors per
track) = 101760
Note 5:
The number of cylinders for a CVS volume is calculated as follows (
↑…↑
means that the value should be rounded up to the next integer):
OPEN-3/8/9/E: The number of cylinders for a CVS volume =
# of cylinders =
↑ (capacity (MB) specified by user) × 1024/720 ↑
Example: For an OPEN-3 CVS volume with capacity = 37 MB:
# of cylinders =
↑37 × 1024/720↑ = ↑52.62↑ (rounded up to next integer) =
53 cylinders
OPEN-V: The number of cylinders for a CVS volume =
# of cylinders =
↑ (capacity (MB) specified by user) × 16/15 ↑
Example: For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders =
↑49 × 16/15↑ = ↑52.26↑ (rounded up to next integer) = 53
cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume =
# of cylinders =
