Gents, I have alerts in PRISM " Upgrade NGT version on VM to latest " to all VMs.
Must I start one by one ? what's steps should I do ? Is there any effect in VMs ?

I have 19 VM's with this warning while >100 without issues, I feel that the NGT update was part of the AOS update but for any reason it failed on some VM's (ie on one particular VM I had to update the "lvm2", and on another one I was unable to mount the cd, even manually).
If we solve the pre-requisites, is there a way to relaunch the NGT update for all the ones that aren't up-to-date ?
I tried a "bulk" unattended NGT upgrade on TWO Windows VMs through Prism Central 5.10 once, but it failed with waving flags. I have yet to investigate why.
Even if you upgrade your VMs from their console one by one as I do, there is some risk of very briefly disrupting the VM's network connection. Some productive applications tolerate that, some don't.
There was a situation on our clusters where NGT ISO wouldn't mount. (There must be only one empty CD-ROM attached.) I found that in our case the Hypervisor thinks the virtual CD tray is "open" and therefore no ISO (not just NGT) can be mounted. The CD tray can only be "closed" with a VM powercycle/reboot or per host through a cli script.
