Calculate vxfs millisecond delay
We have a Netbackup master server cluster, the catalog/DB is sitting on a vxfs volume. There is a case open currently with Veritas and they have found massive delays (40 seconds!) at backup peak timeon the Sybase database and have recommended we do a "nbdb_unload -rebuild" and "nbdb_admin -reorganize". Meanwhile, we are looking at the IO on the catalog/DB volume. The technote below says the response shouldn't be more than 20ms. How do I determine the current response time, is there a Storage Foundation tool that can provide this? Our host is running RHEL6.6.Solved1.3KViews0likes2Comments

Troubleshooting volume performance in Storage Foundation
Hi, all. We have released a set of articles about troubleshooting volume performance in Storage Foundation. Here is the link: "Troubleshooting volume performance in Veritas Storage Foundation" http://www.symantec.com/docs/TECH202712 Since this is a broad topic, the "technote" is actually a set of about a dozen article that have been organized into a logical tree structure, with TECH202712 at its "root."
