higher than the limit is one that has a blocked request problem.
(2)
Hiproc: A disk with request rate per second higher than the request
rate limit and high queue time is a disk with high request rate.
(3)
Indexd: An index problem is detected when a disk has high queue time
and cache call per request greater than the cache call ratio limit.
(4)
Memory: This problem is detected when a disk has high queue time
and a shortage of memory.
(5)
Overbs: An overbusy disk with high queue time or a disk with high
queue time and its backup on a slower processor are considered
overbusy.
(6)
Pcache: A disk with high request queue time and cache hit rate lower
than the low limit of the cache hit rate is a disk with poor cache.
(7)
Queued: A disk that has request queue time greater than the limit is
considered a disk with high queue time.
(8)
R:C <1: The ratio of disk requests to cache requests less than 1.
System Recovery Performance Score Grading
The system recovery score is based on the ability of the system to provide acceptable
performance if a CPU fails. Example 4-40 is a detailed report displaying the System
Recovery Score.
