As for stackers directly attached to the filers, what have folks found that works? When we first tried this (long ago with an ADIC DLT 2500xt "stacker"), we found that the stacker mechanism was quite lousy and tended to hang. Thus we had to reboot the filer to "un-hang" the stacker. I have stayed away from diretly connected drives since.

I used directly attached DLT-4700s at Netapp and never had one with a hung stacker mechanism. If the UNIX host firing off the dump over rsh died, it *could* leave the dump/drive hung and thus requiring a reboot of the filer to fix, but that was rare.
