esxi LUN initialize inside physical server with windows 2003

[AviGrinberg]

Hi,

I've 2 esxi 5.0 and i use veeam backup and replication and i exposed the LUN that the esxi work on to the veeam backup to do SAN direct backup.

when i go to the disk management on the windows 2003 veeam backup server is see that he initialize (not formatted)2 disks out of the 4 disks(LUN) that he see.

is it ok?did i mess up something in the VMFS datastore?

Welcome to the community.

Below is my understanding.

You have ESXi and VM.

the VM is presented with RDM HDD(RAW DISK MAPPING).

When you login and see the disk are shown as intailize, it will be showing like that.

just click on intialized and format the disk and use it.

If above is not your configuration, then Could please put it clearly.

no.I've 2 esxi with 4 LUN shared together.

i\ve physical server that run veeam backup on windows 2003 SP2 32BIT.

the 4 LUN that the esxi see i have present it to the physical server so the veeam backup will do SAN direct backup.

when i have present those 4 shared LUN to the physical server i see in the physical server on the disk management that 2 LUN are initialized

and other 2 are not initialized.

i've read somewhere that if the disk is initialized then the esxi will not see this LUN anymore because the signature or something like that is change.

is it true? if so how can fix this issue so the esxi will continue to use the LUN after reboot.
