Hi All,
The available_media script in /usr/openv/netbackup/bin/goodies is a dog
for sites with a large number of tapes.
I've rewritten this script in perl for performance and was wondering if
anyone who uses the veritas version would like to test it.
On our system ~1400 carts the veritas version takes ~55 minutes. This
version takes ~12 seconds and emulates the output, including the -summary
option.
Things to note:
- added -size option to display data sizes in Ki/Mi/Gi
- added -pool= to only show a specific pool name
- added WARNING lines if multiple mediaids are found in the MM
(remove or filter these lines if you depend on the output
format)
- my perl is weak - please submit improvements after which I'll
make it generally available somewhere else
- only tested with nbu 4.5 under AIX
- don't forget to update the script with the location of perl
on your system
I hope someone finds this useful.
- Dale
