It sounds like a hardware problem.
Did you check EREP?
Of no of SIOs decrease, it is probably due to increased Dasd response times.
Did you check this? What component of Resp time increases?
Does the other LPAR use the same Dasd

z/OS 1.8 is unsupported.
When we power on reset the CPU and IPL from that,It works

Please describe your 'simple dump'. Memory dump? Dump of volsers? Is it dump by

Hi Manshadi,
You might check to see if you have Defined Capacity or Group Capacity setup on
the HMC for the LPARs on this CEC.
This would fit with the general symptom of IPL and then sometime later seeing a
slowdown. You said 12 hours but I want to consider that might be subjective
and not

Well this is interesting:
Excp, Conn are the same!! Apparently there is no difference in the actual I/O.
TCB and SIO are higher. What is SIO, where does this come from? What is the
relationship between Excp and SIO? Do you use hardware
SIO means Start IO and it's came from SDSF panel during execution a job.
About hardware compression I should investigate.

Well
Is you z/OS V1.8 system have all maintenance available? There were some
issues with SRM and some of the counters going negative. But I do not
recall where that was.
I would search IBM Link and see if there is any remaining maint you do not
have on. Even though z/OS V1.8 is no longer supported,
Isn't capacity capping a 4 hour rolling average? So wouldn't it kick
in before 4 hours?
Unless the workload is slow for about 9 hours, then CPU utilization picks up.
