In this video, Russ Long dives into the details of troubleshooting common virtual machine issues within a DRS enabled cluster. Learn how to keep VMs running in your DRS clustered environment.
- [Narrator] Now we are going to look at the lowest level…of our DRS cluster, the VM's.…This is the whole reason for virtualization,…so let's look into why VM's could have trouble…within our DRS cluster.…Our first troubleshooting mantra…within the DRS cluster at the virtual machine level…is CPU and memory resources.…A yellow or red cluster in our status means…that there are currently not enough resources…to meet the reservations of a pool for the virtual machines.…
The VM that is having the issue…may be getting starved out…so check your resource pool allocations…to ensure that this is not the case.…Another reason you could see a VM begin to flounder…is the limits for our resource pool is set too high…or share values may be set incorrectly.…Take a look at not only the VM,…but the resource pools in which it resides,…and even resource pools that come out of…the same parent pool.…
We next would like to check…on the cluster resources available.…It could simply be insufficient for what the VM requires.…Contention could be the issue here.…
