I have been having performance problem with few hosts connected to XP12K. After some digging in I found that MP's,where these hosts are conected are running > 75%.
front end ports for these MPs are shared by 5-6 servers only and one of those is having performance issue.
Now, how can I know which host/LDEV is generating $tupid IO and filling up the whole MP?
PA doesnt show much and it's hard to get info for each LDEV from SVP monitor.
Is there any script/tool/cli you guys have? which can give me ldev IO for a list of ldev;s?
Thx again in advance.
Solved! Go to Solution.

SolutionIf you know which LDEVs are assigned to individual host, look at them (you can see maximum 8 at a time, so you may need to work hard). Individually you can look for
-LDEV total IO
-LDEV MB Matrix
then pick the dirty apple from the group and shift it to another port.
Worth to add that having 75% utilization is not that bad, worry when it reaches 85-90%.
My 2 cents worth.

Re: XP12K Performance Issue.
What command do you use? I tried ldev but results doesnt look true. It doesnt match with svp output either.
Thx again,

ExportDB -st 11.27.2007 06:00:00 -et 11.28.2007 18:00:00 -hr -dver 020000 -dkc 11783 -file xyz -auth administrator:password
you can always look for exportdb help with -h option.
