The above is an old 1G SCSI drive. Would that explain the missing options?

Given that both AWRE and ARRE are 1, what action should I take now? As a side note, both vinum drives (da1 and da2) had AWRE and ARRE set. da0 didn't but now has these values set. thanks greg. -- Dan Langille - DVL Software Limited [I'm looking for more work] http://www.dvl-software.com/ | http://www.unixathome.org/ http://www.racingsystem.com/ | http://www.freebsddiary.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
