MSA 2050 3 nodes in nodes 100 disk usage in VM hyper-v slow work

[techdaw]

Hi i have problem with MSA2050

3 nodes hyper-V 2022 in cluster CSV all ports connect to switch FC NX9000 Cisco

On 1 nodes VMachines in hyper-v  disk usage on 1-30%

but other nodes this same in VM  or second disk usage 100% usage R/W 3000 ms I cant find problem, 

All check Latest firmware on MSA 2050, switch cisco etc...

VM instaled exchange 2019 problem problems work create DAG etc database .

Thanks for sugested what command use to identify problem.

Change all map to volumes, change Tier afinity Preformance and problem sitll exitst but is smaller

R/W in VM machines is 1-2500ms and smaller lag in vm machine.

On cluster HPV warning exist

Cluster Shared Volume 'Volume1' ('Dysk klastrowy 2') has entered a paused state because of 'STATUS_IO_TIMEOUT(c00000b5)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Problem with veeam time out for snapchot created.

In logs from nods

Hi,

The issue description is not quite clear.

Please provide the following information:

1. Are you facing the performance issue on vms hosted on all MSA volumes (identify whether the issue is on Pool A volumes or Pool B volume) ?
2. Are you facing the latency only when load/vm is on Nodes 2 and 3? I believe any vm hosted on Node 1 performs better compared to vms hosted in Nodes 2 and 3.
3. Have you checked the SAN switch logs for any port error or low RX/TX power on SFP modules?
4. Have you tried shutting down one storage controller at a time to check whether the issue follows any specific controller?

I would suggest getting an HPE support case logged to rule out any issues from MSA storage end.
These type of issues requires extensive log analysis and a support case would help.

AD1  now performance issue on vms hosted on only volumes PoolA 

AD2. all nodes 

AD3. What is vaule normal RT/XT power ?

AD4. How to turn off controler ?

[ArunKKR]

Hi,

Optimal RX/TX power values should be above 400uW.

Launch an SSH session to MSA controller IP and share the output of the below values:

show system

show pools

show disk-groups

show ports

show host-port-statistics (execute this command 3 or 5 times during a period when latency is observed)

show disk-statistics

[techdaw]

Power on switch.

Hi, 

The Majority of the RX/TX power values seems to be with in normal range.

I would suggest engaging Cisco FC switch team to check for their suggestions where the values are below -5dBM

Reference:

https://www.asc.ohio-state.edu/smith.2341/dbm2power.php

MSA is not reporting any issues.

There does not seem to be much IOs either on Pool A or Pool B volumes and no latency is being reported in the output shared.

The command to shut down controller A would be shutdown a

You could restart it after the testing using the below command:

restart sc a

You would need to log a support case to further review the store logs/debug logs.

If restarted controler A i need close all connectio to storage ? or can i restarted online ?

Yest I open support case.

Thanks for answers and sugestions.

Hi, The entire load will be on single controller while controller is restarted. It can be performed online. However, it is recommended to be restarted during a period of low IO activity.

Hi, Those are read response times and any thing below 20000 should be fine.
