question about symmask command by using the replace action

Question

Hi I have a question. I'm going to reinstall a server due to I need to reorganize my AIX Server, the problem is: I assigned disk to it 6 month ago, but to reinstall the server I have to move its disks to another new server in order to maintain the producction in other server, in the meantime, i reinstall the old server. Does any one know how to do that? I was thinking about the symmask command by using the replace action, something like that symmask ¿sid 814 ¿wwn 20000000c920b484 replace 20000000c920b393 Before to do this I have to configure a Zoning in my cisco Switch so that the new server can see the vcm lun before the replacement. Let me tell you that I going to clone my operating system to avoid a new database and application installation. The other question is: What happens with Power Path and the EMC ODM for AIX, when I clone my operating system I'm going to copy both into the image I create, do i need to do any thing additional to reconfigure powerpath or EMC ODM for AIX in my new server? I'll appreciate your help on this. Best regards

I'm not an AIX expert .. I can only say that the command you posted will actually remove wwn 20000000c920b484 from masking database replacing it with 20000000c920b393, thus removing access to old HBA and granting access to new HBA upon 'symmask refresh'.
