If you want LVM to watch out only for certain type of devices, you have to put an appropriate filter. e.g to exclude CDROM you may put filter = [ r|/dev/cdrom| ] Given your requirement, you may try filter = [ a/sda[1-9]$/ a/emcpower.*/ r/.*/ ] And don't forget to run vgscan -vv after making changes to lvm.conf, also be careful if running on production, keeping the backup of lvm.conf is must.

Is there a way we can tweak the ulimit - user limit for all users.

In my opinion you're trying to solve the wrong problem. Giving
untrusted users admin access on production systems is going to keep
causing problems, regardless of how many such vulnerabilities you
close. The real solution is to remove admin access from all except a
few experienced users.
If you can't do that, give each one of them a virtual machine to play
with and let him/her destroy it in whatever innovative fashion s/he
finds convenient.
