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?

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. I can’t find any info about whether it’s safe to do this in production, so to be on the safe side I placed the hosts in maintenance mode first. Enter Maintenance Mode Use the following command; vim-cmd /hostsvc/maintenance_mode_enter Disable ATS Heartbeat Use the following...

Virtual SAN: Suppress ‘Datastore Usage on Disk’ Alarm

KB ID 0001527 Problem While deploying a HPE StoreVirtual VSA this week. We noticed all the local Datastore were showing an ‘Alarm’. If you are unfamiliar with Virtual SANs, then you give all the LOCAL Storage to them, which then gets ‘aggregated’ and provided back to the host(s) as fault tolerant clustered storage, like so; Which is great, but the VMware hosts just see that their LOCAL Datastore(s) are full,...

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...
