x4500 Disk Mapping

Akairenn — Tue, 03 Nov 2009 14:11:51 +0000

Disk mapping for the x4500 (aka, Thumper). Mileage may vary, depending on phase of the moon, firmware update status, operating system/distribution, solar flares.

Yeah, Linux Is…

Four Port Link Aggregation on Solaris:

dladm create-aggr -d e1000g0 -d e1000g1 -d e1000g2 -d e1000g3 1 ifconfig aggr1 plumb 10.103.0.13 up dladm modify-aggr -L active -T short 1

Four Port Link Aggregation on Linux:

modprobe bonding mode=* miimon=100 ifconfig bond0 hw ether randommacaddress ifconfig bond0 10.103.0.13 up ifenslave bond0 eth0 ifenslave bond0 eth1 ifenslave bond0 eth2 ifenslave bond0 eth3

I won’t even get into the simplicity of Solaris’ persistent configuration vs. Linux’s persistent configuration – which will change between distributions, even.

The more I play with Solaris and OpenSolaris, the more I’m forced to admit that Linux is a mere toy compared to either.

Three commands and link aggregation just works. No hassle. No debugging. No conflicting instructions on how various bits should be configured. No trying to figure out what mode to use, or why your selected mode isn’t working despite the fact that it should.

It’s unfortunate Solaris requires a logical method of thinking. More people should be using it. The learning curve is supposedly steep – I dare say it is, when you’re used to the nonsensical environments of Linux, Windows or even OS X. Do yourself a favor and try to get past that.

Once you start discovering why things are so obviously set up the way they are, you’ll pause, perhaps scratch your chin, and say, “Damn – why the hell isn’t that other operating system like this?”

Quick and Dirty Solaris 10 Network Configuration

The folllowing example assumes a single interface using an IP address of 192.168.42.2.

/etc/hosts:
# # Internet host table # 127.0.0.1 localhost ::1 localhost 192.168.42.2 mybox mybox.somedomain.com loghost

Make sure you leave the loghost bit in on one of your interfaces.

/etc/netmasks:
# 192.168.42.0 255.255.255.0

This is where you set netmasks for the networks in use by your devices.

/etc/resolv.conf:
nameserver #.#.#.# nameserver #.#.#.#

Naturally, replace #.#.#.# with the IP addresses of your nameservers.

/etc/nsswitch.conf:

Look for the following line:
hosts: files

Modify it to read:
hosts: files dns

/etc/defaultrouter:
192.168.42.1

This is the default gateway for your system as a whole. Sanity insists gateways are usually placed on the .1 IP of a network; your mileage may however vary.

Tying it all together with /etc/hostname.*:
Your hostnames (for each interface) go into an interface-specific file. For example purposes, I’m assuming an ‘e1000′ networking device, with a single port.

/etc/hostname.e1000g0:
mybox.somedomain.com

Review:
Roughly, your device gets its hostname from the /etc/hostname.* file. It uses this to link up with /etc/hosts and /etc/netmasks to get IP information for itself. In a simple world, the default gateway in /etc/defaultrouter is all you need for an initial, working route. Finally nsswitch.conf is set to allow dns lookups for hosts.

Now when you bring up your box, your networking is good to go with no further screwing about.
