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...

Stacking (VSF) Aruba Switches

KB ID 0001492 I noticed some shiny Aruba switches on the bench today, they were for a job my colleague is working on. (Note: Each switch in a stack should be the same, so these will need two stacks!) I work on the occasional HP/Aruba core switch, but it’s been a while since I did any work on distribution switches like these. The first thing I learned, was there’s no dedicated stacking cable for them. They simply use a 10Gb...
