System logs for the RHEL based systems can be found at
/var/log/messages. Depending on the period of time a problem is occurring you may need to gather more than just the most recent logs. You should find additional logs with either a sequence or time stamp on the end of the file (ex:
StorNext also has a utility for gathering StorNext logs called
cvgather. This also collects some system info.
To gather the most info use the DVS command line utility
dvsutil_getconfig (note: some systems use an alternate
dvsutil_getconfig-mds so please use "tab command-line completion" or navigate to
/usr/local/bin/ to find the correct version for your system.)
