Of course, if cables are pulled out or something like that, I'm not expecting the OS to recover from that. :-) I'm not trying to recover from or survive physical configuration changes. I'm more interested in what happens when a volume generates a temporary error, such as the ones that sometimes occur when doing logical configuration changes (BIN-file changes on Symmetrix, for example). > >When making an online configuration change on the Symmetrix (such as > >remapping volumes), it is possible for the attached hosts to experience > >a temporary error while accessing a storage array volume. For example, > are you sure this tech note will still apply with the DMX? I'm not sure, but that doesn't apply to us anyway since we have a 8530. Anyway, I'll take a look at the SCSI_TIMEOUT value.
