Why are the log files filling up with iSCSi failure messages being suppressed
I have a Cx3-20c array running the R2.26.020,5.032 code.
This log files are filling up with "Some iSCSI failure messages are being suppressed"
These messages are being reported at the exact same time every day.
The array is also reporting the following error on SPA every day or 2.
The iSCSI module of physical port 0 has experienced an internal error
and has to reset. Info0: 56 info1: 4377.
SPA has been replaced and the errors still show up.
Has anyone seen anything similar to this?

This is most likely a problem with the configuration of the iSCSI connections from the hosts to the array and the use of subnetting for the iSCSI connections.
On PowerLink see Support Solutions emc246921 for this issue and also emc245445 for a list of best practices when using iSCSI. For host connections see emc156408.

Check if the iSCSI connections on the array are configured properly. I had a similar error of "iSCSI module resetting" show up twice every week, the problem in my case was that all the IPs were in a single subnet. We divided IPs according to EMC recommendations and haven't had any issue since then.
