Veritas Volume Manager (VxVM) on AIX 5.3

I'm a fan of VxVM, I've use over many years. But I did get to a problem that stumped me recently. I was unable to initialise the disks on AIX, I would get a permission denied error. aix53# /usr/lib/vxvm/bin/vxdisksetup -if DS4700-0_1 format=aixdisk /dev/hdisk3: Permission denied Resolution. The DS4700 storage must use AIX multipath MPIO and that needs the right reserve policy. (VxVM's DMP only sees a single path) aix53# chdev -l hdisk3 -a reserve_policy=no_reserve Config Aix 5.3 TL8 SP2 DS4700 Firmware 9.6x VxVM 5, MP1, Rolling Patch5, HotFix 5
