To bring only some resource of a service group offline.To bring down a resources dependencies must be taken into account.Listener should be brought down first before bringing down oracle. And then the disk mount points.

Command syntax :

hares offline sys

root@sbimum66 # hares offline Netlsnr_bvsbi1 sys sbimum66

root@sbimum66 # hares offline oracle_sbi sys sbimum66

To check the status of the resource use the command

# hastatus -summ

If the output does not have any W_OFFLINE then it can be confirmed that the resource has gone offline.

The output will also show state as PARTIAL against the service group name.

In case any resource is faulted and if any other resource is W_OFFLINE state then try to offline the resource.

If not possible then turn offline the entire service group. Clear the fault for the entire service group and then bring the service group online.

Eg :

root@sbimum66 # hagrp offline sbivcsfs-rg sys sbimum66

root@sbimum66 # hagrp clear sbivcsfs-rg sys sbimum66

After clearing the fault check the status with

# hastatus summ command and if no faults are displayed bring the service group online.

root@sbimum66 # hagrp online sbivcsfs-rg sys sbimum66
