Problem

Customer has 4 new LUNS - couldn't get vxvm initialized.

Error

VEA: V-40-49408-40 Disk cannot be read

From command line - vxdisksetup -i got V-5-2-2480 error

Cause

Known issue with these devices and 5.0MP3.

Solution

Format and label the devices to be EFI.

Example:

# format -e /dev/vx/rdmp/ams_wms0_121

... select 'L' label

format> l
[0] SMI Label
[1] EFI Label
Specify Label type[1]: 0

..asked if you want to continue, answer 'y'.

Then 'q' to quit.

Run 'vxdctl enable'

Example:

# vxdctl enable

Then vxdisksetup -i on the device.

Example:

# vxdisksetup -i ams_wms0_121

For VxVM 5.0MP3 version, these luns can only be initialized in 'sliced' format.

Note: 5.1 RP1 EFI luns can be initialized as CDS.
