ASM and SAN HQ Issues
Hi,
I am encountering a couple of issues in ASM 4.6 and SAN HQ 3.0.
SAN HQ 3.0:
I get email alerts saying that the network connectivity has failed even though there are no issues with network connectivity. The message is below:
- [ID: 14.2] Unable to establish connection.
- The SAN HQ server issued SNMP requests at the group, some or all of which failed. This condition is likely due to network congestion or failed network connectivity. The server will retry within 60 seconds. Check your network connectivity and check that the storage group is online. If the problem persists, contact your Dell support provider for assistance.
ASM 4.6:
For some reason when ASM is refreshing the host, it never completes with one of the hosts (in a cluster). It stays stuck at Discovering Cluster Connectivity and I don't understand why. I'm also getting email alerts saying that the Smart Snapshots have failed.
Can someone please help?
Thank you.

There is SANHQ 3.0.1 available from eqlsupport.dell.com/.../download.aspx
From the release notes:
Items Fixed in SAN HQ Version 3.0.1
The following issue has been fixed in the SAN Headquarters version 3.0.1 maintenance release:
Previously, after upgrading to SAN HQ 3.0, the SAN HQ server might not connect to groups running firmware version 7 and higher, and SAN HQ issued an alert (SAN HQ Event ID: 14.2) stating that some or all SNMP requests at the group failed.
This condition is resolved.

Welcome to the club.
We are facing the same issue after upgrading to SANHQ 3.0. We get these messages 2-3 times per day.(not every day).
Every 24-36h it goes worst and SANHQ lost contact to our 2nd EQL group. We need to restart the EQLperf service to get it working again. A [tag:SR] is pending.
Regards,
Joerg

Yep, we're seeing the same thing. Only had a couple of these message recently but still interested to see if it's the new version or our network that is the problem

You can try to increase the timeout under Settings->Server Settings-> ICMP Ping timeout to see if this helps.

Same issue for us, I am trying Joerg's suggestion (increasing ping timeout from 2 to 4 seconds)

@rb51,
maybe you can open an #SR because as more ppl complaining about the issue it will fix faster. Otherwise you can omit the notification for that specific event.

@Joerg
Workaround did not work for us.
I am logging a [tag:SR] today as suggested.
Thanks again, ric

Getting the same error after upgrading to SANHQ 3.0
[ID: 14.2] Unable to establish connection.
The SAN HQ server issued SNMP requests at the group, some or all of which failed. This condition is likely due to network congestion or failed network connectivity. The server will retry within 60 seconds. Check your network connectivity and check that the storage group is online. If the problem persists, contact your Dell support provider for assistance.
SR opened with Dell, working through compatibility checklist - Network switches, NIC's, etc.

Hi,
got Feedback from Dell Support:
"An update to the 3rd-Party library used in SAN-HQ 3.0 has been seen as the root-cause of the events and threshold discrepancy.
A fix is being actively worked for the next release of SAN-HQ, with the workaround in use until that point in time."

Joerg

You can disable the notification about this event. Restart of the service is needed than. Support told me that there is no schedule yet for the next version.

We get these too. All hours of the day. Set timeout to 60 seconds and still happens.

Do any of you have one of the SR #'s that's been opened? I want to piggy back on it with our Dell account.
