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...
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...

KB ID 0001176 Dtd 16/04/16ProblemI 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...
HP Networking – Tracing Networks and Locating IP addresses
After not touching one for a couple of years, I was back on HP switches recently, and I had to map out a clients switches. Now I could have used some software, but they didn’t have SNMP enabled so, I had to ‘re acquaint’ myself with LLDP. For a basic LLDP View of attached devices.
