Not mandatory but at this point to do will do some (evils) tests. Too see, simply remove one of the disks from its bay without doing anything else :-).
If you have configured the power-management of the SAN box (see above paragraphs), you should have noticed that the format command returns something (e.g.
c7t0d0) just before the # zpool status san pool: san state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM san ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c7t0d0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 errors: No known data errors # # df -h Filesystem Size Used Avail Use% Mounted on (...) san 8.1T 45K 8.1T 1% /san The above just says: everything is in order, the pool is fully functional (not in a DEGRADED state).
If you create some activity you will see the pool switch in degraded state: # dd if=/dev/random of=/san/count=1000 # zpool status san pool: san state: DEGRADED status: One or more devices has been removed by the administrator.
Sufficient replicas exist for the pool to continue functioning in a degraded state.

When idle with all of the disk spun up, the SAN Box consumes near 40W at the plug when idle and near 60W when dealing with a lot of I/O activities.It is possible that your drives come with preconfigured values preventing them from being spun down before a factory-set delay or being spun at all (experiments with our WD Caviar Green drives are put in standby with a factory-set delay of ~8 minutes).With the hardware used to build the SAN Box, nothing more than 27W is drained from the power plug when all of the drives are in standby and when the CPU is idle (32% more energy savings compared to the original 40W) :-).The whole process of setting up a Solaris operating system won't be explained because it far beyond the scope of this article but here is some pertinent information for SAN setup thematic.A few points: You can, as an alternative, grab the Solaris Express 11 live CD image and install the system from there.However we are not not lawers nor Oracle commercial partners so always check with Oracle to see if they allow you to freely use OSE 11 or if they require you to buy a support contract in your context. Open Indiana build 148 supports ZFS version 5 and zpool version 28 (encryption is provided in zpool version 31, that version is, to our knowledge, only supported on OSE 11) Each of the two wthernet NIC will be connected to two different (linked) Gigabits switches.
