If you are using a LSI Logic 92xx (ie, 9211-8i, 9211-4i, 9200-16e, etc) SAS2 controller for your OpenSolaris or NexentaStor storage machine (Solaris-based distributions use the mpt_sas driver for these), you may have had trouble finding the utilities to manage it from a command line (this is useful to force a rescan, bus reset, blink a drive, etc.) I also had these issues awhile ago, and ran across the utility at SuperMicro’s FAQ site (of all places!) I still haven’t found an official download link (at LSI, or in the ‘downloads’ section at SuperMicro), but if you are looking for them, you can find them at:
The zip file includes the utility for DOS, Linux PPC, Linux x86 (which will also work on x64), Solaris Sparc and X86, and Windows 32-bit and 64-bit.
Here’s hoping these appear somewhere a bit more official sooner than later, and in the meantime, I hope this helps someone find them!
