Hi,

In one of the HP-UX servers i am getting the following error.

/opt/system/bin/backup.sh[872]: TAPE_TOTAL[1]: bad number
/opt/system/bin/backup.sh[872]: TAPE_TOTAL[2]: bad number
/opt/system/bin/backup.sh[872]: TAPE_TOTAL[3]: bad number
fbackup exited with Status 4 - Possible causes are new tape or no dates file

It seems the script errors at line 872:

while [ ${NUM_LOGS} -gt ${BACKUP_TAPES} ]

Something is wrong here in the context of the script but I'm not a script specialist to tell you what is wrong with this line...

Hi

2 problems

1)fbackup returns one of the following values:
--------------------------------------------

0 upon normal completion.
1 If it is interrupted but allowed to save its state for possible restart.
2 If any error conditions prevent the session from completing.
4 if any warning conditions are encountered.
If warnings occur, the operator should verify the
fbackup logs to justify the sanity of the backup taken.

4 can be returned if files were open during backup

2)The script error

put set -x

after line 1 and run it

You see what is happening then

Line 784... you're doing a numeric comparison (-le), but you have TAPE_TOTAL[${TAPE_NUM}] as a string by enclosing it in double quotes.

This does not set a value to the variable -
echo "BACKUP_TAPES=21"
I do not see where this is actually being set, thus a bad number.

[ ${NUM_LOGS} -lt ${BACKUP_TAPES} ] || {
while [ ${NUM_LOGS} -gt ${BACKUP_TAPES} ]
