On the new M4000, with install of vxvm/vcs 4.1, we came across a problem that “vxdisk list” only recognize the internal disks, it ignores all the EMC disk, though they are visiable from format command.
Had tried “vxdctl enable” “vxdisk scandisks”, “cfgadm -c configure c2; cfgadm -c configure c4″ “restart vxvm daemon”, still no luck.
Since solaris is already able to see and use the EMC disk, something wrong with the device descovery with Veritas vxvm. So we digged around with vxddladm command.

After includearray of libvxemc.so, the disks will be gone again, we must exclude this library to get it going.
Not sure what is the side effects of excluding libvxemc.so, Rohana had logged a call with Veritas and will follow it up.
