Statistics in the Storage Adapter panel are aggregated per storage adapter by default. Statistics can also be viewed per storage path.

The following table displays the interactive commands you can use with the storage adapter panel.

Table 2. Storage Adapter Panel Interactive Commands

Command

Description

e

Toggles whether storage adapter statistics appear expanded or unexpanded. Allows you to view storage resource utilization statistics broken down by individual paths belonging to an expanded storage adapter. You are prompted for the adapter name.

r

Sorts by READS/s column.

w

Sorts by WRITES/s column.

R

Sorts by MBREAD/s read column.

T

Sorts by MBWRTN/s written column.

N

Sorts first by ADAPTR column, then by PATH column. This is the default sort order.
