Hi,
I can't find any documentation of all available mount options of mount -v cifs
Unfortunately you can specify any fantasy options, no complains, and the mount command shows this option
In particular I want to know if there is a possibility to completely disable cifs caching in aix, like dio/cio for jfs2
Thanks in advance
Cheers funksen

hi, sorry for my late response, was on vacation 
thank you for the link, really couldn't find it, was looking for cifs and not smbfs
unfortunately the options are very limited
cifs is the official name for smb(fs). I have not looked at the article, so I am not sure how current, or not current it is.
So, the fileset name uses the official name, the documentation talks about the well-known name.
Even back when the cifs fileset was introduced - LONG LONG ago...
From: AIX 5.3 Differences: Paragraph 7.12 (very little, actually no detailed information) link: http://www.redbooks.ibm.com/redbooks/pdfs/sg247463.pdf
Example 7-18 Configuring SMB clients
# lslpp -L |grep cifs
bos.cifs_fs.rte 5.3.0.0 C F Runtime for SMBFS
bos.cifs_fs.smit 5.3.0.0 C F SMIT Interface for SMBFS
# lsdev -C|grep nsmb
nsmb0 Available N/A
Re: the Knowledge Center Link - the options are different, and limited because jfs/jfs2 and SMB are very different file system types. Looks like besides who owns what there are also limitations re: max. file size that can be transferred.
If you are running into a limitation of the AIX cifs (client-side or server-side), or even to get your question answered about what options have any effect - open a PMR. Questions like that fall under your software support question.
The hardest part is presenting a well-formed question!
