Pinned topic VIO Server and the R2 copies of EMC Symmetrix disk

‏2009-05-19T20:02:17Z |
I have a vio server that now has the r2 copies of an EMC LUN attached (to be used for DR) and while I can see the hdiskpower I do not seem to be able to make a vdev with it. The error is:
method error (/usr/lib/methods/cfg_vt_scdisk):
0514-047 Cannot access a device

Is this because the disk is the R2 copy and set to read-only? And if so does that mean I will need to wait until I need them to make the vdev, etc?
Thanks in advance.

    I think this needs to go to AIX Support for further investigation on the status of your LUNs.
    There are so many permutations and combinations to work through and this is near impossible via a Forum.

    I have seen this before. In order to create the vdevs you will need to stop the SRDF sync and run cfgmgr on the vio servers to clear the locks on the disks. You should then be able to create your vdevs and then restart you sync's.

    Be aware that if you ever reboot your VIO servers the R2 vdevs will be set to a defined state. If you need to failover to the DR environment you will need to break the sync again and run cfgmgr on the vdevs (cfgmgr -vl <vdevname>) to return them to an available state.

      i am facing the similar issue - VTD's configured with EMC R2 devices are going to defined state after reboot.

      Could some one please help me how to avoid this issue and make VTD to available state upon VIO server reboot..?

    I have not had the time to test this out but what I've been told there is an attribute associated with the VTD that ignores errors and allows for this configuration. The attribute name is "mirrored" which can have the value "false" or "true". The default is false.
