Hi techies , Can u pls guide me to check q depth value in current environment in command suite ?
thanks in advance
I had to look for that on my ESXi host. Also FC driver had to support qdepth lookup.
Here is the command I ran on ESXi version 5 with QLogic VIC FC driver:
. You can check the current queue depth with this command:
esxcli system module parameters list -m fnic
Set a queue depth with this command (for example 8):
esxcli system module parameters set -p fnic_max_qdepth=8 -m fnic
Default is 32 on VMware.
With the current HCS (7.6.x), it is not possible to check queue depth values.
Thanks Dang Luong for replying to my post .can u pls tell then how we can able to find the q dept value or how can i find the exact value of the current set up.
Are you looking for the queue depth for the servers? We'd need to know the OS & HBA types.
Queue Depth (throttle) value is set on HBA and is a way to limit the number of SCSI commands that can be simultaneously send on a single LUN visible via HBA as the queue depth supported by Storage Port has a particular limit.
As of now I have not come across and HDS tool to find Storage port queue Depth utilisation.
Are u facing any kind of performance issues on hosts connected to the same pair of Storage ports?
Are there large number of luns on those Storage Ports?
We are using Q Logic HBA and AIX 6.1 Operating system. Is there any option to check the Q depth value other than server side ?
Currently, there is no way to check this from the array side.
Are u thinking of changing the queue depth???
