The two disks on the 2940UW cards function without a problem The 300GB disk (raidv box) on the 3940UW has difficulty doing a dump. A level 0 dump of 75GB that should take less than 9 hours takes upwards of 24. Unlike one of the other disks that takes only 8 or 9 hours. All disks on the machine are different. some output...
