Not many replies to this one and in the end i got the drive and backup
scripts working again by using 'ipcs' to display all the active semaphores
and 'ipcrm' to remove them. once they'd been removed the backups started
working OK.
cheers,
john

hi all -
my overnight backups to an HP DLT4000 8-tape library have just started
failing with the following error

anyone any idead what this means ?
this is on an AlphaStation 500/500 with Tru64 v5.1 PK6.
if i 'manually' load a tape using mcutil i can read/write to it OK but
my backup shell script produces the errors above.
TIA,
john
