Sequential Write Cache Hits  Frontend
The identification number of the subsystem.SS ID
The SLPR group ID.
NOTE: SLPR does not exist in the P9000 disk arrays. So,
the SLPR group ID is displayed only for the XP disk arrays.
SLPR
The LUN associated with the given LDEV.Target LUN
The volume group identification name if the device is
associated with a volume group. HP XP P9000 Performance
Vol. Group
Advisor reports volume groups from LVM (an HP brand)
and VXVM (a Veritas brand).
NOTE:
• The E-LDEV, Ext-LUN, E-Port(s), E-Seq, Jnl Group, and Vol. Group are available for selection
only if they are configured in the selected XP or P9000 disk array.
• The following metrics are not applicable for the XP or the P9000 continuous access journal
pool LDEVs. NA is displayed:
◦ Response Time Metric category: Maximum Write Response and Average Write Response
◦ Frontend IO Metric category: Random Write Cache Hits, Random Writes, Sequential
Write Cache Hits, and Sequential Writes
◦ Frontend MB Metric category: Random MB Writes and Sequential MB Writes
