HP and Cisco – VLANs and Trunks Confusion!
KB ID 0000741 Problem When I first started in IT, I went and did my Cisco CCNA. So I learned that to connect Cisco switches and pass VLAN traffic between them, I needed to create a ‘Trunk’ to pass the VLAN traffic. Fast forward a few years, and I now work for an HP reseller.

Setup an HP 1800-24G (J9028B) Switch
KB ID 0000800 Problem Essentially you can unbox this switch, plug it in and it will do what you want (unless you have VLANS, or trunks (port-channels)). Which is what my client had done, but I needed to get on the web console and have a look at what was going on, and there is NO CONSOLE socket on this unit at all. Solution 1. Don’t bother looking in DHCP, it’s NOT set to DHCP by default. From the factory the switch will have...

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....

KB ID 0000874 Problem The call came in this morning, a client had replaced a failed drive in his SAN, (an MSA P2000 2324sa). He was asking if there was anything he needed to do. I said “Just mark it as a global spare and that should be it”. He rang back some time later to say he was still having problems. When I dialled on I could see his ‘new’ drive was marked as LEFTOVR and was flagged with the following...

Remove the failed drive, and replace with the new one. 2. Connect to the web cosole of the storage array. Select the MSA > Provisioning > Manage Global spares....
