Just a quick note to remind you all that, if you’ve upgraded the version of PowerPath/VE that you’re using to accommodate the upgrade to vSphere 5 (that is, you’ve moved from 5.4 SP2 to 220.127.116.11), you should have also upgraded the version of rpowermt you’re using. Otherwise, you’ll end up with the following error message when using the older version of rpowermt on newer hosts.
Note that the 5.7.x version of rpowermt works with earlier versions of PP/VE.
I’m not sure why I missed this but I’m nothing if not extremely ignorant from time to time. We’ve been getting occasional Purple Screens on our ESXi hosts running 4.1 and EMC PowerPath/VE 5.4 SP2. Seems it might be a problem that needs some hot fixin’. Annoyingly, you need to contact EMC support to get hold of the patch. That’s not a major issue because if you’re running PowerPath you’d know how to do this, but it would be nice if they just belted it out on their support site. But what do I know about the complexities of patch release schedules? Hopefully the patch will be incorporated into the next dot release of PP/VE, otherwise you should consider getting hold of it if you’re having the issues described by VMware here and in EMC’s kb article emc263739 (sorry you’ll have to search for it once you’re logged in).
Sometimes, and for what seems like no good reason, we have hosts in our vSphere clusters that seem to not have such a happy time with PowerPath/VE. I can tell you the symptoms, but can’t tell you the cause.
It should look like this.
The workaround we’ve come up with is to put the host into Maintenance Mode, uninstall PP/VE, and reinstall.
Here’s the commands you’ll need to run via the vMA. (BTW we still have issues with passthrough AD authentication on the ESXi boxes when using vMA – but I don’t care anymore).
login as: domain\adminuser Using keyboard-interactive authentication. Password: Welcome to vMA run ‘vma-help’ or see http://www.vmware.com/go/vma for more details.
