Re: [Veritas-bu] Strange question

[David Stanaway]

Here is a perl script I use on my master server for checking SLPs in the 
morning.


It my have some win32ism's, my master is W2K8

I would be curious to see nbstlutil list -l output for one of your 
images that shows as COMPLETE


I may need to rework this script.

#! /usr/bin/perl -w

use constant NBSTLUTILCMD => 'nbstlutil list -l';

my %badcopystates = (1 => "NOT_STARTED", 2=> "IN_PROGRESS", 
9=>"NOT_STARTED|INACTIVE", 10=>"IN_PROGRESS|INACTIVE");


#LIST -l columns for record header I
my @STLIMAGEHEADERS = qw(Version RecordHeader Master BackupID Client 
BackupTime Policy CType SType SLP SLPState SLPStartTime DataClass);


#Index it for reference
my %stlimageheadersidx = ();
for (my $i=0; $i<=$#STLIMAGEHEADERS; $i++) {
$stlimageheadersidx{$STLIMAGEHEADERS[$i]} = $i;
}

my $incompletecount = 0;
open NBSTLLISTOUT,  NBSTLUTILCMD . '|';
while() {
chomp;
my @jobinfo = split(/ /,$_);
if ( $jobinfo[$stlimageheadersidx{RecordHeader}] eq 'I'
&& defined($badcopystates{$jobinfo[$stlimageheadersidx{SLPState}]}) ) {
printf ("Got IMAGE: %s\n", $jobinfo[$stlimageheadersidx{BackupID}]);
for(my $i=0;$i<=$#STLIMAGEHEADERS;$i++) {
printf ("\t%s: %s\n",$STLIMAGEHEADERS[$i], $jobinfo[$i]);
}
++$incompletecount;
}
}
close NBSTLLISTOUT or die NBSTLUTILCMD . " completed with error $!";

if ($incompletecount > 0)  {
print "Found $incompletecount images that were not complete.\n";
exit 1;
} else {
print "Found no images that were not complete.\n";
exit 0;
}



Here is another script I was working on but got left on the cuttingroom 
floor.

Re: [Veritas-bu] Strange question

[David Stanaway]

What kind of backups are these?

GRT backups and Synthetic backups to my knowledge result in dataloss if 
used with an SLP expecting the SLP to function.

Hi All,

I ran the nbstlutil command on a particular client with the following 
results (many lines)


Image  for Lifcycle SLP is COMPLETE

   Copy to Disk is NOT_STARTED

   Copy to Tape is NOT_STARTED

What is confusing me is that the image for the specified backupid does 
not exist anywhere that I can find. Bpimagelist --backupid 
 show no entity found.


So how can the Lifecycle be complete if there are no images? The 
actual backup does not exist on disk. The SLP backups to disk then 
copies to tape, ONLY. Also this particular SLP has a retention level 
of infinite. L


Any enlightenment would be greatly appreciated.

Re: [Veritas-bu] Strange question

Patrick,

Which version of Netbackup are you running? In 6.5.x, there are some
conditions in which a SLP process gets status SLP_COMPLETE without all
copies being done.

Now infinite retention is standard as long as slp status is not
SLP_COMPLETE.

[Veritas-bu] Strange question

Hi All,

SLP works.
