HPE MSA Cannot See LUN?
Cannot See LUN KB ID 0001862 Problem I finally got round to replacing the SAN on my test network, I setup the new one via direct cable connection (10Gbps iSCSI DAC). I created vDisks and volumes, presented those volumes. Setup iSCSI bindings in vSphere, all vanilla stuff. ESX hosts could not see the storage LUNS, they could see the SAN, but ‘add datastore’ showed me no available storage. Solution: Cannot See LUN Two...
VMware: Change IOPS Limit From 1000 to 1
KB ID 0001532 Problem I got asked to do this by a client this week, HP has requested that this be set for connections to their Storevirtual VSA that had been having some problems. Solution I followed the instructions and was at first confused because I could not see the settings that needed changing? That’s because this only applies if you have MULTIPATHING enabled and set to ‘Round Robin’. So if your storage does...
Disable ATS Heartbeat
KB ID 0001529 Problem After ESX 5.5 Update 2, VMware added ATS Heartbeat.Some vendors, (like HPE SureStore and VSA) recommend that this is disabled.

HPe Synergy 12000 MPIO QSFP to 10GB SFP Setup
KB ID 0001495 Problem I was recently involved in deploying an HPe Synergy 12000 Frame. And the network connections from it were ‘a little unusual’ so I thought I’d document that here, to save anyone else the problems I had. I was connecting to an HP/Aruba 5412 switch so my cables were all HP/Aruba (to be on the safe side). What you can see (above) is the MPIO Cable (K2Q46A P/N 800867-001) fixed onto the left (and...
HP MSA 2000 G2 Firmware update loop
KB ID 0000248 Problem Seen on HP MSA2324sa G2. You attempt to upgrade the firmware on this unit and, it applies to the first controller, that restarts and then it constantly tries to update the other controller. Solution If you’re reading this then you’re probably already in an upgrade loop? The fist step is to stop it looping then sort the firmware out. 1. Remove controller B (bottom one) from the SAN, (Slacken the 2...
HP StorageWorks P2000 – Connecting to and Configuring
KB ID 0000569 Problem Normally I simply connect a new MSA to a clients network, and it gets it’s address from DHCP. Then I can get the address for the DHCP Scope, and point my web browser at it. Yesterday I was starting with new virtual infrastructure and had no DHCP. With the G1 and G2 models, you got a console/serial cable and could just terminal in. With the G3 they have replaced the serial socket with a mini USB socket....
