SuSE SLES and NETAPP LUN's. How yo grow them?

Hi everyone,

Please bear with what might be a very simple question here. We have a SuSE SLES 11 server which is connected via HBA's to a LUN on a NETAPP filer. This LUN is say 500GB in size and is part of a disk group we have called rootdg, Multipathing is also enabled at the OS I beleive as the issue of the command multipath -ll shows me the paths are active and all is good.

I have increased the size of the volume and then the LUN on the NETAPP to 1TB, check this and the NETAPP reports the correct sizes. The OS is still reporting the old LUN so as I could reboot the server I did. It reboots but still VxFS cannot see the new size. Multipath can as if I issues the same command as above it shows the same paths just with the larger LUN size.

We have tried the command  vxdctl enable but this seems not to work.

On a side not I have tried to install the VOM and put the agent on the same server, this reports the same but does report the disk sdd as the correct larger LUN - Not sure how as this is part of the four paths to the LUN sda,sdb,sdc,sdd.

What am I doing incorrectly? I am a mere beginner in this as you can tell.

Thanks

  • The command you're looking for is 'vxdisk resize'.
