I'm not sure it would even be possible to come up with a worse = interface. It boggles the mind. I recommend you always run with this configuration: # MegaCli -AdpSetProp AutoEnhancedImportEnbl -aALL # MegaCli -AdpSetProp MaintainPdFailHistoryEnbl -0 -aALL AutoEnhancedImportEnbl will bring the foreign disk back in on a reboot. = LSI recommends turning off MaintainPdFailHistory when using single-disk = RAID0 configurations. To bring in a foreign disk without rebooting: # MegaCli -CfgForeign -Scan -aALL # MegaCli -CfgForeign -Import [x] -aN (where x is the config number = listed in the scan, and N is the adapter number) Adding these capabilities to mfiutil is on my list of things to do, but = it's not ready yet. Has anyone managed to get the real JBOD mode working on this controller? = It advertises support in the firmware but doesn't seem to do anything. = The documentation only lists JBOD mode as a feature of the lower-end = controllers. Hope this helps. -Andrew -------------------------------------------------- Andrew Boyer aboyer@averesystems.com
