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 model, 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...
HP BL460c (Gen 10) Blade No RAID?
KB ID 0001443 Problem While spinning up some new BL460c (Gen 10) blades for a client, I noticed there was no RAID option? They were going to be VMware ESX hosts, and had two SSD drives so I just accepted the default and my ESX server saw a LUN for each drive and I created two DataStores on each host. The client wanted them changing to RAID1 (fair enough) so I revisited the drive setup. Solution WARNING: Before you proceed enabling...
Mac OSX: ‘Cannot Send F11 Keystroke’
KB ID 0001441 Problem I was building some HP blade servers today via iLO, and while trying to install ESX, I reached this stage; Pressing F11 on a mac just increases the volume, and with the other function keys (F1 to F10) you simply press ‘fn’ and the appropriate F key, and it works properly. But not on a mac, ‘Fn+F11’ just shows you your desktop. Even changing function keys in the keyboard settings has no...

HP – Switches The IP (or subnet) Already Exists
KB ID 0001176 Problem I was changing a clients LAN subnet this week, (dropping the mask from /24 to /16). When I attempted to change the management IP on the clients HP switches this happened; HP2510-24G(config)# vlan 1 HP2510-24G(vlan-1)# ip address 10.0.0.250 255.255.0.0 The IP address (or subnet) 10.0.0.250/16 already exists. HP2510-24G(vlan-1)# At first I though the switch was complaining because the IP was remaining the same, I...
