Comment 3 for bug 1317134

Hi Kurt,

For our release product, we have release noted the "host sets" limitation. Meanwhile, we made a temporary fix in cinder/volume/drivers/san/hp/hp_3par_common.py

         try:
             self._delete_3par_host(hostname)
             self._remove_hosts_naming_dict_host(hostname)
- except hpexceptions.HTTPConflict as ex:
- # host will only be removed after all vluns
- # have been removed
- if 'has exported VLUN' in ex.get_description():
- pass
- else:
- raise
+ except Exception as ex:
+ LOG.info("Host '%s' could not be deleted: %s", hostname, ex.get_description())

We should not be removing the host for various reasons (host already exists, host a member of host set, host is a cluster member with other vluns attached, etc.). The host entry should be deleted if it gets created by the driver, but we currently do do that approach.

Thanks for your looking into this problem.
