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 moreHPE CLX Virtual Machine Protection Fails

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 moreHPE 3PAR Remote Copy Volumes Both Read Only

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 moreHPE 3PAR Want List 2017

Well this is an interesting and unexpected announcement – Hewlett Packard Enterprise (HPE) are to purchase Nimble storage. This is in addition to the recent acquisition of Simplivity which is a player in the hyperconverged market.

HPE Discover 2016 Pictures

Well HPE Discover in London was awesome – I must have left an impression last year as various HPE reps around the event remembered me. There was so much to see and I wish I’d taken more pictures but I spent more time talking to people. Let’s take a look at some of the pictures … Read moreHPE Discover 2016 Pictures

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 moreHPE 3PAR Logical Disk Not Mapped to Virtual Volume

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 moreHPE 3PAR Change DNS Settings

VMware ESXi Host Long Reboot due to Fibre Channel Binding

I finally got round to looking at a problem which has existed in one of my datacenters for I guess a few years now. It’s really bothered me for a long time but I’ve just been tied up with other projects so it remained. I have two datacenters which are more or less identical in … Read moreVMware ESXi Host Long Reboot due to Fibre Channel Binding

HPE 3PAR Interrupt Coalescing

I’m currently working on a case with HPE (Hewlett Packard Enterprise) 3PAR support with regard to excessive retransmit errors on our Remote Copy Fibre Channel (RCFC) connection between two 7400 arrays. While troubleshooting we found that a required option was not set appropriately – namely interrupt coalescing on the RCFC ports. In this post I … Read moreHPE 3PAR Interrupt Coalescing

HPE CLX Error – Socket connection timed out to port 2550

This week I came across an interesting problem on one of our Microsoft Failover Clusters (FOC) which utilises the HPE Cluster Extensions (CLX) software to  provide failover support with our HPE 3PAR arrays. A couple of roles within one FOC showed the CLX resource as failed with everything else still showing as online. We were … Read moreHPE CLX Error – Socket connection timed out to port 2550
