EVA6400 high hostport queue depth
Hi,
I have a 2C12D EVA6400 - its reasonably utilised, however after some analysis I noticed that a connected host is reporting a high queue depth on only one controller host port .
when I say 'high' it has been sitting on ~65000 for a long time now.
I am just wanting to try and get some help on how to trace it back to an individual vdisk - or identify if there is a problem with the HBA on the connected host.
I do not see any high latency or high use on any of the vdisks connected to this host.
Name Read Read Read Write Write Write Av. Port Ctlr
Req/s MB/s Latency Req/s MB/s Latency Queue WWN
(ms) (ms) Depth
---- ----- ------ ------- ----- ------ ------- ----- ------------------- ----
FP2 57 0.80 7.7 118 1.10 0.5 65542 5001-4380-025B-A029 L013
Any ideas on how to trace this back through the stack to clearly ID the problem?
There are no errors on any of the SAN switch ports connected to the EVA or the host.
Thanks

Re: EVA6400 high hostport queue depth
In there you could even get statistics down to a single physical disk.
Is this host only accessing the EVA through FP2 on one controller?
This may be of some assistance regarding evaperf:

Re: EVA6400 high hostport queue depth
I am not sure if the host is only accessing it through this port - it is zoned to all ports, and it seems to be able to access via the other controller.
but the high queue depth is still present on this port.
thanks

Re: EVA6400 high hostport queue depth
You should be able to determine which path the host uses by looking at the config for that host in your multipath settings.

Re: EVA6400 high hostport queue depth
sadly its an HP-UX server and I am contracting to this client and cannot seem to contact anyone who wants to assist me with it... :)
I will keep looking - I am guessing its the HBA on the HP-UX host, its an integrity c-class blade server - the HBA type/driver wont even show up on the switches!

Re: EVA6400 high hostport queue depth
Any resolution to this?
I'm experiencing the same thing intermittently. I believe it to be a bug in evaperf causing bogus numbers. I get average queue depth values around 65,000 one one port with no evidence of high IO or latency.
Currently using CommandView EVA 10.3.
