NetApp DataOnTap 8.0.2P2: Sysstat shows only CP Types as "D" -> caused by low datavecs

udo_braunschweiger · ‎2011-10-20

We have a performance case open, no result so far.

I saw that we are having, even if there is low load on the FAS3210, we have a lot of CF Type D

Any hint or idea??

the aggregate consists of two shelfes with 600GB SAS Disk Drives in two raidgroups

Hello,

Did you ever get anywhere with the type D CP's "caused by low datavecs"? I have a 3240 HA/Pair with next to no load on it (one vfiler with several VDI's) and when our vmware admins were vmotioning some machines from the 3170 to the 3240 we saw the following:

(Hardware is 3240 running 8.0.2P4) with Flash Cache Modules and 65 disk aggr of 600Gb SAS).... just not finding much online explaining what the TYPE D really means.

thanks,

Keith
