The "all" option can be used to display EDT entries marked as "not present" or "not connected", which are normally supressed.
The "serial" option will obtain and display the device serial number (if the Inquiry optional vital product data serial page is supported).
The "status" option will issue a Test Unit Ready command and present
device status information (Ready, Not Ready, Busy, Reserved, etc).
[ Added mainly for ASE testing to quickly locate reserved devices. ]
These three options are in addition to the "capabilities" option previously supported. Only one of "capabilities", "serial", or "status" will be displayed (parsed in that order).
scu> set default retries VALUE (where VALUE is range 0 - 255).
This controls the number of retries done on things like SCSI BUSY.
BTW: The only errors automatically retried (if anabled) is BUSY. Retries for "SELECTION TIMEOUT" are no longer performed, so Roger's scripts can detect this error (which normally shouldn't happen).
