Return write access to the primary cluster

When the primary cluster returns to service, you can return write access to data in the cloud to the primary cluster.

1. Perform SIQ resync-prep <policy> on the original primary cluster.
2. Wait until the <policy>_mirror policy exists on the secondary cluster.
3. Perform SIQ sync of <policy>_mirror on the secondary cluster.
4. Perform SIQ allow-write of <policy>_mirror on the original primary cluster.
5. On the secondary cluster, remove write access to the cloud data.

   # isi cloud access remove <GUID>

   where <GUID> is the GUID of the cluster that originally archived the cloud data. For example:

   # isi cloud access remove ab9dd991261e11e382240800200c9a66

6. On the primary cluster, give write access to the cloud data.

   # isi cloud access add <GUID>

   where <GUID> is the GUID of the cluster that originally archived the data. For example:

   # isi cloud access add ab9dd991261e11e382240800200c9a66

7. Wait until source directory on primary cluster becomes writable.
8. Perform SIQ recovery resync-prep of <policy>_mirror on the secondary cluster.
