As I mentioned previously, it’s been a little while since I’ve done things with the Unisphere Host Agent on a Windows physical. However, whether the platform is Linux, Windows, Solaris or Other, you’ll occasionally have cause to direct the Unisphere Host Agent to use a particular IP address when communicating with the CLARiiON, usually because there are multiple NICs configured. If this is the case, check out emc62479 – Ensuring Navisphere Agent binds to correct NIC in multi-homed server with multiple NICs on Powerlink. The upshot is you’ll need to change the NIC binding order in Windows, and create a text file for Unipshere to reference with the correct IP address and hostname. You’ll need to create a file called agentID.txt in the Unisphere Host Agent installation directory. The name of the file is case-sensitive, so, you know, try and get that right. On the first line of the file, put in the FQDN of the host. On the second line put the IP address you want it to use with the Unisphere Agent. Once you’ve done this, restart Navisphere / Unisphere Host Agent on the host in question and, eventually, you’ll notice that the host has the correct IP address in Unisphere. It’s a bit of a PITA, but preferable to not being able to correctly query the host from Unisphere.
Brian at Going Virtual had a great post recently on connecting to the CLARiiON via serial cable. I was all set to do a brief howto article on the various connection mechanisms available on the CLARiiON for service activities and then figured out that the bulk of the work was done. So I thought I’d just add a note that, if you want to connect to the CLARiiON’s service LAN, here’s what you need to do. This is more for my reference, as I always find myself scratching around for the service LAN IP addresses.
Connect your laptop (via crossover cable) to SP Service LAN port.
Set your TCP/IP network properties to the following:
IP address – 188.8.131.52 or 184.108.40.206
Subnet mask – 255.255.255.248
Default gateway – blank
DNS server entries – blank
Note that the Service LAN ports on CX4 are no longer crossed as they were on CX3 series storage systems. When you connect to SPA’s LAN port, you are connected to SPA, and the same for SPB.
You can then connect to either SP thusly:
SPA – http://220.127.116.11/setup
SPB – http://18.104.22.168/setup
