HP StorageWorks Disk Array XP operating system configuration guide: SGI IRIX (A5951-96075, December 2005)

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 = ↑

(capacity (MB) s

peciﬁed by user) × 1024/720 ↑ ×n

Example

For a CVS LUSE volume with capacity = 37 MB andn=4:

# of cylinders = ↑37 × 1024/720↑ ×4=↑52.62↑×4=53×4=212

OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity

(MB) speciﬁed by user) × 16/15 ↑ ×n

Example

For an OPEN-V

CVS LUSE volume with capacity = 49 MB andn=4:

# of cylinders = ↑49 × 16/15↑ ×4=↑52.26↑×4=53×4=212

Note 6:

The capacity of an OPEN-3/8/9/E CVS volume is speciﬁed in MB, not number of

cylinders. The capacity of an OPEN-V CVS volume can b e speciﬁed in MB or num b er of

cylinders. You set the volume size using the Remote Web Console, Command View or

Command View Advanced Edition software.
