Solaris

sir,
i want remove cluster 3.0 from tow sun server 280R shared with tow storadg
A1000.
please advise me.

you will have to boot without active cluster modules with the -x option:
"reboot -- -x" or in OBP "boot -x"
after that the command "scinstall -r" will uninstall the cluster framework. look into "man scinstall" for more information

make sure that your A1000 mountpoints are no longer in your vfstab with the "global" option. after uninstalling the cluster you will have to destroy your metasets "man metaset" for the global devices, if you are using disksuite/svm-lvm or in VxVM deport the multihosted volumes an import it with no options..

tipp: do it one by one, if an error occur you still have an active cluster node...
tipp: do use A1000 on a cluster you changed the SCSI-initiator-ID, remeber that so you won't have problems in the future
