NB: Our SuperMicro machines appear to log SMART failures as OEM #0xff, e.g. ipmitool outputs something like:
| Code Block |
|---|
1 | 08/13/2011 | 07:08:13 | OEM #0xff | OEM Specific | Asserted
|
ipmitool will ask for a password for user ADMIN in all cases. You can avoid this by putting it in a 0600 file and using the -f flag, or passing it on the command line (-P; not super-secure, but our environment is pretty trusted), or putting it in your environment (see the man page).
ipmitw
ipmitool is a bit of a pain to use (lots of arguments, can't specify everything in environment variables or ~/.ipmitool config files, etc, only operates on one machine at a time). That's why I threw together ipmitw (ipmi tool wrap) to simplify things. You can download it here.
All it does is run ipmitool, providing the annoying user/password/protocol args automatically, and executing it once for each host listed. Hosts can be listed in ranges, or comma separated (one contiguous string – no spaces). For example:
| Code Block |
|---|
ipmitw rc01-rc80 power reset (reset power on all 80 machines)
ipmitw 1-80 power reset (same as above, but without rc prefix)
ipmitw rc05,rc10,rc15-20,rc57,82 chassis status (can list hosts, as well as ranges) |
IPMI View
SuperMicro distributes a multi-platform Java GUI app called "IPMI View" that incorporates the above functions, and more. It's a bit slow and not amenable to scripting, but it does support the KVM console, which can be very useful. Note that your machine will have to be on the internal cluster VLAN to access the ipmi controllers.
