John Baldwin	8b22f43d9d	Add the ability to manage the state of write caching when the battery ... back-up is missing or dead. The current state of this field is reported in 'mfiutil cache <volume>' and can be adjusted via 'mfiutil cache <volume> bad-bbu-write-cache <enable|disable>'. This setting should generally be disabled to avoid data loss. MFC after: 1 week	2011-04-05 14:19:05 +00:00
John Baldwin	c02999d982	- Save errno values before calling warn(3) so that errors are correctly ... reported. - Use powerof2() from <sys/param.h> rather than a copy and paste version. Submitted by: gcooper MFC after: 1 week	2010-10-26 19:11:09 +00:00
Scott Long	763fae7918	ntroduce mfiutil, a basic utility for managing LSI SAS-RAID & Dell PERC5/6 ... controllers. Controller, array, and drive status can be checked, basic attributes can be changed, and arrays and spares can be created and deleted. Controller firmware can also be flashed. This does not replace MegaCLI, found in ports, as that is officially sanctioned and supported by LSI and includes vastly more functionality. However, mfiutil is open source and guaranteed to provide basic functionality, which can be especially useful if you have a problem and can't get MegaCLI to work.
