Re: backup issue

hi,


you can use any one of tar and fbackup utility to take your backup?


#fbackup -f -i /tmp -i /sapmnt/PRD/exe -I /var/backup.index

for this--------->And one more thing,VG00 is having free PE.SO can I able to extend the LV without rebooting and going to single user mode


if you are using vxfs filesystem then you neither reboot nor go to single user mode .
you just follow the steps as:

#lvextend -L /dev/vg00/lvolname /dev/dsk/diskname

If you want to mentioned the name of disk for Correspondence PVs.

#umount /mountpoint

#extendfs -F vxfs /dev/vg00/rlvolname

#mount /dev/vg00/lvolname /mountpoint

Re: backup issue

If you have online jfs

#cd /
#lvextend -L size_in_mb /dev/vg00/lvolxx
#fsadm -F vxfs -b size_in_mb /usr

Work is life, you know, and without it, there's nothing but fear and insecurity.

Re: backup issue

first check if you have OnlineJFS

# /usr/sbin/swlist | grep -i online
B3929EA B.11.31 HP OnLineJFS (Server)

if you have the online JFS, use VVS commands

for backup
find out which tape dev to use

#/usr/sbin/ioscan -fnkC tape

#tar cvtf /dev/rmt0 /tmp /sapmnt/PRD/exe
