HPE CLX Virtual Machine Protection Fails

Recently a colleague was attempting to configure the cluster extension protection (CLX) which is required by our Active/Active HPE 3PAR storage setup. Our Microsoft Failover Clusters are stretched over geographically separate sites and the Cluster Share Volumes (CSV) are spread over the 3PAR storage arrays in each site. We use the CLX software to manage … Read more

HPE 3PAR Remote Copy Volumes Both Read Only

I recently ‘enjoyed’ working on an issue where a 3PAR remote copy group issue resulted in both virtual volumes entering a read-only state. I’ve seen a similar problem where both copies go into a read-write state which is probably more worrying when it happens. Let’s take a look at the problem, the data I had … Read more

HPE 3PAR Want List 2017

I still remember being impressed with the design and architecture of the HPE 3PAR storage system all those years ago when going through a tender process for a replacement SAN. Over time new versions of the hardware and software have been released and again I’ve been impressed and excited to see the new possibilities. I … Read more

HPE Discover 2016 Slides and Presentations

I meant to post this shortly after the HPE ‘Discover’ event in London last December but unfortunately it slipped my mind and it was only this week when I went looking for a particular presentation that I remembered.

HPE C7000 Blade Chassis SSL Certificate Replacement

The SSL/TLS certificates on my HPE (Hewlett Packard Enterprise) C7000 blade chassis expired this week and therefore required replacing. I’m a strong believer in always replacing certificates with valid ones generated by a certificate authority (CA). In my mind there isn’t much excuse in a business to not have an internal CA for this sort … Read more

HPE 3PAR Logical Disk Not Mapped to Virtual Volume

I came across this issue while reviewing the output of the checkhealth –detail command run from the 3PAR command line. This command provides a more detailed view (as per the switch) of any health issues including those experienced in the Logical Disk (LD) subsystem.  The specific error ‘LDs not mapped to a volume’ may happen … Read more

HPE 3PAR Change DNS Settings

I recently setup a DNS iApp on the F5 load balancers in my datacenters and felt it was time to migrate the Hewlett Packard Enterprise (HPE) 3PAR storage arrays DNS to point to this new virtual IP (VIP) rather than to the static DNS server it currently used. I will demonstrate the command line syntax for … Read more
