wrong with secondary disk.

Hi ,
I have a problem with the secondary disks when I run command 'sanlun lun show -p' and I don't understand what it means and don't know how to fix it? Please help.

More information is needed:

First of all, your command appears to be a script as I cannot find any 11.xx command matching it. If it is an HP delivered command, please provide the full path. If it is a script, please attach it in your next post.

Also, help us understand the designation of primary/secondary: are these mirrored? Are these boot disks? Since all of them have a common designation cxt3d0, you appear to be setup with two HBAs on a dual fabric SAN, such that you show 4 paths to the disks.

Perhaps you should be speaking with your SAN administrator and verifying that all of the zoning for paths and disks are correct. You should likely run the command,

# /opt/fcms/bin/fcmsutil /dev/tdx where "x" represents either 0 or 1 as you have apparently two HBAs, td0 and td1. This can give you good information, and you may want to rerun the command with the additional parameter, "vpd" - in case you need to verify the HBA card/driver information.

Once we have some more info, we can proceed!
