Disk Failure in Shared Disk Group configuration!!!


Hi Experts,

If we create a shared disk group with detach policy as 'local' and fail policy as 'leave', what will be the consequences if a disk on which a mirrored plex is situated, fails or corrupts fully. That is, the disk now is wiped out. I have seen that, If the policies are global and dgdisable respec., the disks is replaced. I think relocd has played a role in this. Whether there is role played by relocd in the previous scenario?

Thanks

    Have a look at vxvm admin guide...

    http://sfdoccentral.symantec.com/sf/5.0/solaris/pdf/vxvm_admin.pdf

    page no 416.... that explains the local detach policy & very next page explains leave fail policy...
    a very nice chart is given which tells what happens if any sort of failure happens...

    if failpolicy is set to leave & master has some issues, a panic will be initiated...

    Let me know if you have any further queries after that..
