32 KB - BC Tape Backup

[NBU2010]

Hi Forum,

My Setup : Master/Media Sol. 10 (With latest KJP & OBP) - NBU - 6.5.5

I m facing problem of getting 32 KB for some / all streams for some BC Tape backup. We usually mount FS (Through bpstart script) on media server and take backup. Some or all the streams are writing 32 kb completes successfully (STATUS 0). When FS check on media server, mount point has data.

Same after firing 2-3 times it starts writing.

Sample bpstart script.

set -x
#!/bin/ksh

if [ $COUNT -ne 2 ]
then
sleep 600

vxdg -C import RETIXOS
if [ $? -ne 0 ]

fsck -y -F vxfs /dev/vx/rdsk/RETIXOS/ixosdata > /dev/null

mount -F vxfs -o ro /dev/vx/dsk/RETIXOS/ixosdata /BCV/IXRETPD/ixosdata
if [ $? -ne 0 ]
then
exit 1

Any suggestion as to y this is happening.

Thanks in Advance.

Hi Mate,

Please check the below command, Some time the mount volumes are not proper mounted. Hence we are getting 32KB with successful.

df -k | grep -i mnt

If you run it manually, does it mount the volume?

You might have uncleaned lock files lying in /var/adm/IXRETPD/streams

Hi Baski,

when we mount it manually it does get successful without any issues. lock files are being cleaned when unmounting happens ....here is the output of bpend....

-----------------------------

set -x
rm /var/adm/IXRETPD/streams/LOCK.$1.$2.$3.$4.$BACKUPID
COUNT=`ls -l /var/adm/IXRETPD/streams | wc -l`
if [ $COUNT -ne 1 ]
then
exit 1
else
umount /BCV/IXRETPD/ixosdata
sleep 2
vxvol -g RETIXOS stopall
sleep 2
vxdg deport RETIXOS
fi

Put some sleep time in the bpstart that mounts it. (more than the 2 seconds you have in bpend - I would put at least 30 seconds)

Just to make sure it has time to mount before the jobs starts

Hi J. Hinchchliffe,

Where exactly i can put sleep in bpstart....

after every dg import....volume start...fsck or mount.

Thanks
