"[RTWR-1003], 20384, FID 128, INFO, DELLBC03FM, essd0:RTWR retry 44 to domain" What are these?

Getting these every few seconds on a blade center switch but alos SAN-wide.  A blade center switch was rebooted to fix a problem and these started to occur.

Reliable Transport With Response is trying to reach a domain, and has exceeded the number of times allowed by the code.


If you had provided the entire message, I could tell you which domain to look for.


Run 'fabricshow'. Identify the domain that the message is intending to reach(after the word 'domain' in the message). If that domain does not appear in the fabricshow, find out why it is not online, or is not a member of the fabric.


If the domain target in the message is online, and is present in the fabric, depending on the model you may want to try a hafailover, or hareboot, to kick off the RTWR daemon, should it possibly have been corrupted. If it is a switch which has no failover or is not a 'high availability' product, you may have to reboot that switch. If all else fails, capture the supportsave from the switch and open a service case with your service provider.
