    hi list,

    I found a solution about how to use two 7204 share disk for redundance in
    HA environment.
    The detail is use two SCSI-2 Differential Adapter each node connect to two
    7204 box.
    one 7204 is another 7204's vg copy.

    reference from :
    http://www.tu-darmstadt.de/hrz/unix/ibm/documentation/HACMP/install/ch02.html#200457

    But i donn't know, can AIX do the SCSI adapter failover when one way is
    failed?
    Or I have some misunderstanding?

    Thanks in advance.

    Best Regards.
