SAN file system mounted as read only

Hi

We have a VMAX 20K. And storage was given to a Linux AS 6 server. This was a database server and suddenly the san volume "/db" went to in to read only mode in the middle of the week. The error message fromsyslog shows the following message . Opened the case with EMC. After going through the host grabs and the Symmetrix Array they did not find any issues. Any body can help me to decode these messages.

We need to find the root cause for this.
