[TEST] #3 Modified pool.py to support RPCS CreateResourceInPool.
Patch 3:
--------
1) Moved get_sto_vol_rasd() to pool.py as get_sto_vol_rasd_for_pool(),
since it is used in RPCS/13*py and RPCS/14*py
Patch 2:
-------
1) Added check in get_stovol_rasd_from_sdc()
2) Added get_diskpool() to pool.py as it is used in 10*py/11*py, RPCS/12*py
and will be useful for further tests as well
3) Added rev for storagevol deletion
NOTE: Please base this patch on the patch "Modifying common_util.py for netnfs"
Patch 1:
--------
Added the following two functions which are used in RPCS/10*py and RPCS/11*py
1) get_stovol_rasd_from_sdc() to get the stovol rasd from sdc
2) get_stovol_default_settings() to get default sto vol settings
Also, modified common_util.py to remove the backed up exportfs file
Added RAW_VOL_TYPE which is the FormatType supported by RPCS currently
Once this patch gets accepted we can modify RPCS/10*py to refer to these functions.
Tested with KVM and current sources on SLES11.
