the first 2 digits after the device 0x1f=31 is the driver of the device i.e. sdisk. The following 2 digits 0f=15 is the instance number of the device. Hence you are seeing most of the devices for this XP512 on path c15t#d# have timed out. However, they have eventually come back online. You might want to investigate the reason for such timeout. Could be san issue, pv timeout value, XP controller busy/bottleneck etc.

another thing, look at the ems events captured in the file /var/opt/resmon/log/event.log. That will probably show you all the events related to the messages you saw in the syslog.log.
