EXAMPLES
The following example displays the collection of statistics:
cli% statch -iter 1
12:47:54 04/06/06 r/w I/O per second KBytes per sec Svt ms IOSz KB
Util %
Ldid Ldname LdCh Pdid PdCh Cur Avg Max Cur Avg Max Cur Avg Cur Avg Qlen Cur
Avg
-----------------------------------------------------------------------------------------
total t 0 0 0 0 0.0 0.0 0.0 0.0 0
0 0
For the previous example, before the statch command was issued, the setstatch start
command was issued for chunklets 0 and 2 on logical disk vv0.usr.1 and for chunklets 0 and 1
on logical disk vv0.usr.2.
The columns in the example above are identified as follows:
• Ldid. The logical disk ID.
• Ldname. The logical disk name.
• LdCh. The number of LD chunklets.
• Pdid. The physical disk ID.
• r/w. The I/O type. Values can be read (r), write (w), or read and write (t).
• I/O per second Cur. The current number of I/O per second.
• I/O per second Avg. The average number of I/O per second.
• KBytes per Max. The maximum number of KB per second.
• KBytes per Cur. The current number of KB per second.
• KBytes per Avg. The average number of KB per second.
• Svt ms Max. The maximum service time in milliseconds.
• Svt ms Cur. The current service time in milliseconds.
• Svt ms Avg. The average service time in milliseconds.
• IOSz KB Cur. The current I/O size in KB.
