Hi Folks,
Can you clarify my understandinging?
I have added an extra disk into a server, however when I view it from mylittleexpensiveserver02 I get a different view see below
I dont understand why I am seeing different views of the storage unless server02 is looking at it down a different scsi bus?
Any help appreciated

Hi Steve,
On server 1
fas31400_4 auto - - error
& on Server 2
fas31400_3 auto - - error
both above might be same disks however names are appearing different. I am saying this because I see other three Netbackup disks available already. The numbering here depends on how the device tree was built by operating system & then by veritas in same order.
If you want to make sure that above are same disks, you can run a /etc/vx/diag.d/vxscsiinq command on these disks to find their serial number. If these disks are same, their serial numbers should be same.
As the disks are appearing in error state, it is possible that paths to disks are inaccessible. Paste below output to confirm
server01 # vxdisk list fas31400_4
server02# vxdisk list fas31400_3
Were these devices labelled at operating system ? what is the OS version & vxvm version ?

Hi G
It looks like we have found the inconsistancy

On Server 1, the serial number of disk is
Serial Number : 2Fht/?Cl7FP/
On Server 2, serial number of disk is
Serial Number : 2Fht/?Cl7FPb
which is different with a last digit, can you double check with storage team if these are indeen same Luns or different ? Though vxscsiinfo shouldn't report inconsistencies but here the difference is of 1 digit (last one) , would be better to confirm with storage team about both these Luns.
from vxdisk list output, the paths to disks are enabled. have you tried doing a fdisk, layout a partition table & then do a "vxdisksetup" on the disk ? I am assuming this is new disk & there is no data on the disk.
