[Veritas-bu] bulk import of images

Step 1 - Create MediaIds.txt with the media to import

Step 2 - Assign the media to something that is NOT scratch using the
following command.

for /f %%c in (C:\temp\impt5\MediaIds.txt) do vmchange -h <master> -p 12
-m %%c

The -p 12 is the volume pool number of where you want the media to go.

Step 3 - Stage I Import

for /f %%c in (C:\temp\impt5\MediaIds.txt) do bpimport -create_db_info
-id %%c -L C:\temp\impt5\%%c.txt

Step 4 - Run this script to populate .csv file with media, image and
image info

#Open CSV File for Output
open(DAT1, ">Catalog_media_rpt1.csv");
#Find all the <mediaid>.txt files
open(FIZZLE,"dir /B *.txt |");
#Parse the directory for Media IDs
while (<FIZZLE>) {
if (m/(.+)\.txt/) { $mediaid = $1;
#Open <mediaid>.txt file
open(DAT2, "$_");
#Parse <mediaid>.txt file for image names
while (<DAT2>) {
if ((/^Backup-ID/) || (/^Copy Frag/) || (/^\s/) || (/^---/)) {}
else {
if (/(\w+)\s/) {
$image = $1;
#Run bpimage list to get image information

open(FIZZLE1,"bpimagelist -U -backupid $image |");
while (<FIZZLE1>) {
if (/[0-9]/) {print "$mediaid,$image,$_\n";}
}}}}}}
close(DAT1);

Sorry for the difficult to read perl, I threw this together quickly.

>From this point I put the .csv into excel and created a pivot table with
backups of which servers when.  Then I manually imported whatever images
were required.  If you wanted to simply pahse II import everything you
could simply run another bpimport command in a for loop.

Good luck!

I would be interested in that as well.
