After adding some SAN storage to my UCS Blades, they displayed an error in vSPhere that said “Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version.
My volumes were already the latest and greatest at VMFS5 so I turned to trusty google. Apparently this is a known issue affecting vCenter Server 6.0. It said to restart the management agents on each host to clear up the issue, sweet. I logged onto each host using the DCUI and proceeded to restart the management agents…the error never disappeared. Grr. Digging a little deeper I found that some people who fixed it were doing it through the command line. Both methods should do the same thing but I gave it a shot. Sure enough, connecting to each host via putty (ssh) and running the “services.sh restart” command did the trick. It may throw some alerts but you shouldn’t lose connectivity to anything and the alert will promptly disappear.
