The last couple of weeks more blogs and topics appeared around the warning VirtualCenter gives when there’s no service console redundancy. Several people posted about a workaround to clear this warning. The workaround is very easy: temporarily assign an additional nic to the service console vSwitch and reconfigure your HA. Notice that I used ” workaround” cause I definitely don’t see this as a solution for the problem. With the current technology there’s not much reason not to have a redundant service console in my opinion, especially when you are using HA. I know a nic hardly ever breaks but in this case probably more than 8 VM’s rely on this nic, the physical switch and the network cable it’s attached to. [Read more…] about Service Console redundancy
When using vmpmotion.pl on Windows with the RCLI installed you will need to set some extra environment variables before the script will work. First besure that the Perl filetype is correctly setup. [Read more…] about Using vmpmotion.pl on Windows RCLI
In my RSS reader I noticed a blog on VM/ETC about independent disks and VCB. The thing is, no snapshots are created when a disk is in independent/persistent mode. This can be a problem when you want to use VCB on all your disks. But this can also come in handy when you want to disable a specific disk from being picked up by VCB. For instance a Database server with a 1TB D: disk is probably not a candidate for for VCB in a normal situation. But when setting the D:\ disk in independent/persistent mode this disk will be skipped by VCB because it’s impossible to snapshot a disk that’s in this mode. This way you can dump the C:\ aka System partition and restore the VM in case of disaster recovery more easily.
