My Server went into a faulty state since the database could not write on the partition. I found out that the partition went into Read Only mode. Finally to fix it, I had to do a hard reboot.

Your Emulex card (logline: lpfc 0000:29:00.1: 1:1305) saw a disconnect event on its Fiber Channel port. The ext3 filesystem therefore had trouble saving it's journal. You will probably have to fsck them when the connection comes up again. As with all hard disconnect events, there is a risk of dataloss, but it should be limited to unflushed dirty pages.

As for the Oracle (from your LVM naming scheme, it looks to me) environment, I'm not qualified to guess how much hot water you're in.
