Fsck me! May I ask what is confusing you here?
Which part of "Run fsck manually" is causing you confusion?

What was the partition mounted as?
What was the file system? Ext3? Reiser? Or what else?
Did you properly umount the partition before running fsck (or run fsck from single user runlevel or boot a Live CD)?

Usually 'fsck /dev/somepartitionname' will do ('fsck /dev/sda2').

You need to make backups if you want to ensure you don't lose data. What you backup depends on what is crucial to you. For home users that would be minimally /home and /etc. Where you store backups depends on what resources you have (CDROM drive, external disk or networked storage), what your backup scheme will be (daily incremental, weekly, etc, etc), what the risk is of losing the backup (physical medium damage, bit rot, inadvertent deletion etc, etc) and how fault-tolerant the medium is (think tape vs disk drive vs CDROM). How you make backups depends on your needs. You could simply backup /home like 'tar -cjf /mount/external_disk/home.tar.bz2 /home' or use 'rsync' (also works efficiently with remote or LAN machines). YAST or webpin allow you to search for software, try "backup" or else try http://en.opensuse.org/Special:Search.

While booting it was giving error on /dev/emcpowera1 and going to single user mode.

Usually 'fsck /dev/somepartitionname' will do ('fsck /dev/sda2').

Its a very very critical system that's in production. and the lun is oracle lun. So i backed up the data using veritas netbackup. tried a restore before doing the fsck.

then i executed the bellow command

# fsck /dev/emcpowera1

it asked for some fixes and completed successfully with out any data loss. now my the system is up and running. thank you very much for your time.
