Automatically Configuring ce Cards in Solaris Comments Off on Automatically Configuring ce Cards in Solaris

In 2005 I was having some issues with big F15k domains. They have a mix of 1gb/s and 100mb/s network cards, which all used the same Solaris driver family. Setting the port speeds meant editing the ce.conf file, and any typos or mistakes here either hung the kernel on boot (not good news in a big F15k domain) or just ignored the settings.

I ended up writing a script that would automatically work out what ce cards were present in the Solaris domain, and then automatically generate a ce.conf configuration file. The script grew in complexity when it became clear the F15ks and mid-frame machines (SF6500 etc.) had a radically different PCI addressing scheme.

I ended up writing and submitting a tech tip to Sun’s BigAdmin website. You can read the whole sordid story at http://www.sun.com/bigadmin/content/submitted/config_ce_cards.html

Redundant NICs on Solaris Comments Off on Redundant NICs on Solaris

In June 2001 I wrote an article for SysAdmin Magazine showing how to script NIC failover in Solaris. IPMP wasn’t introduced until the 10/00 release of Solaris 8 (or MU2 if you’re keeping score that way). At the time the environments being managed were Solaris 2.6 and Solaris 7 – the site upgrade to 8 was a long way off.

So I came up with some scripts to enable NIC failover between two ethernet interfaces on the same VLAN. The script itself was pretty basic and relied on ndd and ping – a bit belt and braces, but as the article explains, there were no other cost-free options at the time.
