Oracle ASM Header Backup -- Update

This post will be an update to a post that I made on Thursday, December 09, 2010 about Oracle ASM Header Backups.  

There are multiple ways to skin this cat.  Another option for backing up your ASM file headers is to use "kfed".  Yes, I know, Oracle Support doesn't recommend that we use it.  However, if you ever need to recover the header, you will be very glad you did.  Below is a partial example of a backup using kfed:

/u01/app/oracle/product/12.1.0/grid_1/bin/kfed read ${ASM_DEV_DIR}/${i} text=${HDR_BACKUP_DIR}/${i}.${TODAY}.bkp

Utilizing "kfed read" will allow you to recover the header in case of corruption.  If you have header corruption and your other methods of header backup (like md_backup and dd's) do not work, then you can tell Oracle Support that you have a kfed file of the header from before the corruption.

As with any corruption, make sure you open an SR with Oracle Support before attempting any repair yourself.

For more information, review the information in My Oracle Support (MOS) regarding kfed.
