Martha - I don't think the DS4xxx class systems are specifically qualified for Linux on Z - they are not in the device compatibility matrix as far as I can tell.
But - if you hide them behind a SVC then they are supported, indirectly. Linux on Z supports SVC and by extension any disk that SVC itself supports. SVC in turn supports DS4xxx and lots of other stuff, not just IBM branded disk. Anything you plug into SVC, and is supported by SVC, is by extension supported by Linux on Z. SVC is the San Volume Controller - it's basically an X series box that you dedicate all the SAN volumes to, then it aggregates them together and hands space back out to host systems. Like Minidisk - or more like SFS, really, but for the SAN. -- Jay Brenneman ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
