Why do you think so? Usual file manipulation programs like tar,cp and mv are not available from ASM. ASM is proprietary thing, rather complex, which locks you in with backup solutions (RMAN only) and makes simple things like writing crontab "cleanup" scripts rather difficult. If possible, I would opt for HP's Polyserve or VCS, rather then ASM. ASM is free, thus forced down my gullet, but I don't like it at all. GFS is also a good alternative. Matt Zito's Gridapp has a great deal of experience with Red Hat's GFS. The only thing that ASM has going for it is its price. It's worth every penny you pay for it. So is Polyserve.

Unfortunately so. I would try avoiding it by any means, except by using OCFS. OCFS is badly maintained, has a ton of bugs and is rather unsafe for use. So, if you can't get a decent commercial clustering filesystem from your management, ASM is a thing to try. The bucks thus saved will probably be spent on configuration and work.
