I have several hosts that have RDM's (they are the bane of my existence) which is causing VERY slow ESXi boot times (4+ hours). I know there is a KB on how to fix this by running:
esxcli storage core device setconfig -d naa.id --perennially-reserved=true
And I've already created a script to apply this to all the needed datastores (80+ for each host). Typically this wouldn't be as bad of an issue but to top it off we're having serious storage issues and bad controllers on the storage array. This is causing hosts to stop responding and causing all kinds of other nice issues. Which typically means these hosts end up getting rebooted before I can run this script (obviously can't run the script when the host is hung and not responding) however while the host is up and online is there an advanced setting that anyone might know that I can change the timeout default time and retry count that can be applied now? You're not using host profiles.
Any other fixes than what's listed in the KB would be greatly appreciated.
