Storage Pool Expansion on EMC VNX/MCx arrays is a simple, straightforward task that can be done to increase capacity, performance or both. It is an online operation (NDU) but I always try to initiate it when load on an array is non-peak. The process is just like a Fast VP data relocation. Of course there’s […]

I recently showed this to a colleague who is new to Linux. It should be part of your minimum capabilities as an admin. Manipulating disks/volumes on a guest VM is a task we all have to do. In this post I’m going to detail how to add a new disk to an Ubuntu VM, online. Call […]

A frequent topic on various EMC forums is how to layout Storage Pools according to EMC best practice, typically regarding about what Drive count to use in the RAID config. The best practice documents* is the source of truth for this when creating pools, but what about when you expand Storage Pools? Of course the […]
Most of the time, tasks we start in vSphere just work. That’s why we love it. Queue ’em up, and move onto something else. Sometimes though, they go bad. They freeze, stick, die or just plain error out. This happened to me last week. After changing the scratch location for hosts in a dev cluster, […]
The VNX2/MCx Array release by EMC in 2013 highlighted the whole “multi-core everything” (MCx) software upgrade to make best use of the available CPU cores in the Sandy Bridge Xeon E5 Processors. This allowed for greater parallelism of tasks and big performance improvements across Data services and functions. I’m not going to detail it further […]
Running the dbmaintenance utility regularly is a great way to get the Commcell database in ‘primo shape. Over time, data is aged, clients are reconfigured/deleted and this can all add up to indexes getting out of date, oversized tables etc. It’s recommended to do a Full DBMAINTENANCE operation every 6 months, as per CommVault latest […]
