RE: Disk Replacement

Pro's/con's of unload/reload versus replacing a series of drives online.

Pro's of unload/reload
1)  When you restore it will make intelligent decisions as to the order to 
restore logical files.  This will help it to reuse access paths if you 
previously created logical files in the wrong order.
2)  Should balance your disks better, thus increasing performance.

Pro's of replacing a series of drives online:
1)  No downtime.

Point of information:  The odds of missing something during an 
unload/reload are a lot smaller if your read the B&R V5R3 manual 
carefully.  Then even suggest running the 
RSTLIB SAVLIB(*ALLUSR) DEV(TAPxx) MBROPT(*NEW) ALWOBJDIF(*ALL)
to get those logical files, etc that might be in different libraries.

Question:  If I save access paths (which dramatically reduces the restore 
time) does the system still try to recreate logical files in the order 
that best allows the reuse of access paths?
