When you request a port summary report, the total I/Os displayed may not be equal to the sum of I/Os

across each of the ports. This can occur if multiple paths to an LDEV exist. The port I/O summary

indicates the I/O ceiling values across the ports. It does not indicate the absolute or accurate I/O

rate across the ports.

Working with LDEVs

If LDEVs are associated with multiple RAID groups (such as in 4D+4D configurations where the LDEV

is mirrored on two different RAID groups), these multiple RAID groups are treated as separate sets of

items. For example, if you have an LDEV with RAID group 1-1 1-2, you must select 1-1 1-2 in the

drop-down menu. An LDEV mapped to 1-1 1-2 is treated separately from a RAID group mapped only

to 1-1 or only to 1-2.
