mksysb to directory fails

[bi]

I'm trying to do a mksysb to a dedicated filesystem in rootvg. The command smit issues is:

/usr/bin/mksysb '-e' '-i' /mksysb

The return I get is:

Creating information file (/image.data) for rootvg..

Creating list of files to back up.
Backing up 63894 files

backup: 0511-089 Cannot open /mksysb: Cannot write to a directory.

0512-005 mksysb: Backup Completed.
The backup command completed with errors.
The messages displayed on Standard Error contained additional information.

Owner of /mksysb is root:system and permissions are 777. the /mksysb filesystem is in the /etc/exclude.rootvg file.

I've checked the error codes but can't get any usable/understandable info about the codes. Any idea what I'm doing wrong and how to fix it?

Thanks for any help.

here is what I use
/usr/bin/mksysb -e -X -m /mksysb/rebel_mksysb > /var/adm/mksysb.log 2>&1

plamb,

Thank you. It's working. I guess since I just specified the directory and not a file for it to be put into, that is why it was failing.

I appreciate it.
