Hello,
I have a performance problem on an AIX box. I'm not sure what is causing this and hoping someone may have suggestions. Currently I'm noticing that cpu's are waiting while the box is in a idle state. I checked the disks and none of them are at 100%. If they were then I would understand the wait issue. I'm thinking that the problem might be in the network between the SANS and the box, but I cannot prove that. Please help.
thanks
Are you out of memory or swap? Here are some commands that may help: lsps, sar. topas, iostat, vmstat. The SAN disk would show up as an iostat or %wait in topas issue and not a network issue.
Thanks,
I ran iostat and the results were interesting. The iowait was at 9% but the % tm_act for the disks were not high (The highest one was 6.4). So, why are they waiting if none of the disks are at a high percentage?
What type of SAN system do you have? How is the system connected to the SAN (direct, through 1 switch, 2 switches, etc)?
