of new volumes. Following changes are implemented
1. Disable or enable a pool with the updateStoragePool api. A new 'enabled'
parameter added for the same.
2. When a pool is disabled the state of the pool is updated to 'Disabled'
in the db. On enabling it is updated back to 'Up'. Alert is raised when
a pool is disabled or enabled.
3. Updated other storage providers to also honour the disabled state.
4. A disabled pool is skipped by allocators for provisioing of new volumes.
5. Since the allocators skip a disabled pool for provisioning of volumes,
the volumes are also not listed as a destination for volume migration.
This a NexentaStor iSCSI volume driver.
Now implemented only following functions:
* create volume
* delete volume
Currently delete volume still in progress.
