your system from a previous installation of EVFS.

On systems with PHCO_32488 and VxFS (the EnableVxFS bundle), you must install patch
PHCO_37228.
Recommended Patches
For systems running 11i v2 Update 2, HP recommends that you install the following patch:
PHKL_37146. HP strongly recommends that you install this patch, which fixes a defect that can
cause the newfs or mkfs command for an EVFS volume to fail on systems with components
that call alloc_fake_device(), such as systems that are NFS clients. See “Possible Device
File Collision” (page 29) for more information.
System Reboot
You do not need to reboot if there is no previous version of EVFS installed.
