Hi everybody,
I have deployed ESXi 5.1 on an HP P2000 G3 iSCSI array (see my post on this at http://communities.vmware.com/thread/402472?start=0&tstart=0). So far I have had no issues, but recently I have noticed something:
There are errors logged regarding iSCSI. I have first seen them when upgraded my array's firmware and had to restart ESXi. I am able to reproduce them by rescanning the adapters. Here are the errors:
Login to iSCSI target iqn.1986-03.com.hp:storage.p2000g3.111812a1a4 on vmhba37 @ vmk1 failed. The iSCSI initiator could
not establish a network connection to the target.
Login to iSCSI target iqn.1986-03.com.hp:storage.p2000g3.111812a1a4 on vmhba37 @ vmk2 failed. The iSCSI initiator could
not establish a network connection to the target.
Now, after some research, I found out this is a known issue,
http://vmtoday.com/2012/02/vsphere-5-networking-bug-affects-software-iscsi/
which VMware addresses in a particular way (and claims it was fixed before 5.1 was out):
Well, I've studied the above documents thoroughly (I must also point out the fact that my configuration is similar - I have configured two VMKernels, each of which has the one vmnic active and the other disabled interchangeably).I've tried only the first solution (disable Failback) with no luck. The error is still there. However I have not experienced any issues with my iSCSI links so far. They seem to work fine (at least to my knowledge). Therefore, my questions are the following:
1. Should I be worried about these errors?
2. What would be a quick and simple way to verify the iSCSI links are working OK? Is seeing the datastore mounted and the datapaths 'Active' enough?
I attach some screenshots to illustrate. I will appreciate some response. Thank you.
