Labeling Disk Devices

Each drive used by SNFS must be labeled. A new drive only needs to be 

labeled one time. A drive can be labeled from any StorNext server or 

client that has a Fibre Channel (FC) connection to the drive. Use this 

procedure to label a disk device using CLI.

All output examples shown in this appendix differ from the actual 

output, but the structure and information provided is similar. 

On a SNFS client, at the system prompt, display a list of connected 

drives. Type: /usr/cvfs/bin/cvlabel -l
The command output is similar to this:

Looking at the output information, identify any drives that are 

unused or do not have a recognized Volume Type. For these drives, 

write down their associated device names.

Create /usr/cvfs/config/cvlabels by typing the following:

/usr/cvfs/bin/cvlabel -c > /usr/cvfs/config/cvlabels

The process of disk labeling re-partitions the drives. If you 

select an incorrect drive, you may lose data.

Also, it’s a good practice to save a copy of your labels file. 

If you lose labels (and you using a Linux or Windows 

system,) the Quantum Technical Assistance Center will 

need this copy to help you relabel your devices.
