I need to replace the LUNs in existing coordinator disk group with new LUNs from different array . this is two node VCS cluster. when i try to set below attribute to make it off on the coordinator disk group it is not recognized. maybe is this not the way to set this attribute in this Vertias version.?
we are using Veritas 4.1 version on Solaris 9 Operating system
Any help/suggestion would be much appreciated. Thanks.
In VCS 4.1 there was no method to replace the co-ordinator disk(failed or working) when VXFEN is online.
Attached snippet from the VCS 4.1 Install Guide for replacing the VXFEN disk.
You need to schedule downtime.
Hope this helps.
The flag was not existing in VCS 4.1 & hence vxdg command is not accepting it ..
I agree with Mandar on the fact that you can't replace a coordinator disk online, you need to schedule the outage and follow the method outlined in the guide.
Or you can upgrade to 5.1SP1RP3 which supports both Sol9 and vxfenswap
The vxfenswap utility allows you to replace coordinator disks in a cluster that is online. The utility verifies that the serial number of the new disks are identical on all the nodes and the new disks can support I/O fencing.
4.1 is really old and no longer a supported version
upgrade it to 5.1 is free
