SnapCenter Plug-in for VMware vSphere 5

REST API workflows to mount and unmount datastores

To perform mount and unmount operations for datastore backups using the SnapCenter Plug-in for VMware vSphere REST APIs, you must follow the prescribed sequence of REST API calls.

For each REST API, add https://<server>:<port> at the front of the REST API to form a complete endpoint.

To mount datastores, follow this workflow:

Step REST API Comments

Step	REST API	Comments
1	Go to `http://<vCenter-IP>/mob`	Find the datastore moref from the VMware Managed Objects URL. Note the moref for the datastore that you want to mount.
2	`/4.1/datastores/{moref}/ backups`	`Get the list of backups for a datastore` gets a list of backups for the specified datastore. Pass the moref from Step 1. Note the backupId that you want to mount.
3	`/4.1/datastores/backups/ {backupId}/snapshotlocators`	`Get the list of Snapshot Locations` gets details about the location of the specified backup. Pass the backupId from Step 2. Note the datastore and the location from the snapshotLocationsList list.
4	`/4.1/datastores/{moref}/ availableEsxHosts`	`Get the list of Available Esxi Hosts` gets the list of ESXi hosts that are available for mount operations. Pass the moref from Step 1. Note the availableEsxHostsList information.
5	`/4.1/datastores/backups/ {backupId}/mount`	`Mount datastores for a backup` mounts the specified datastore backup. Pass the backupId from Step 2. In the datastore and location attributes, pass the information from `snapshotLocationsList` in Step 3. In the esxHostName attribute, pass the information from availableEsxHostsList in Step 4.

Go to http://<vCenter-IP>/mob

Find the datastore moref from the VMware Managed Objects URL.
Note the moref for the datastore that you want to mount.

/4.1/datastores/{moref}/ backups

Get the list of backups for a datastore gets a list of backups for the specified datastore.
Pass the moref from Step 1.
Note the backupId that you want to mount.

/4.1/datastores/backups/ {backupId}/snapshotlocators

Get the list of Snapshot Locations gets details about the location of the specified backup.
Pass the backupId from Step 2.
Note the datastore and the location from the snapshotLocationsList list.

/4.1/datastores/{moref}/ availableEsxHosts

Get the list of Available Esxi Hosts gets the list of ESXi hosts that are available for mount operations.
Pass the moref from Step 1.
Note the availableEsxHostsList information.

/4.1/datastores/backups/ {backupId}/mount

Mount datastores for a backup mounts the specified datastore backup.
Pass the backupId from Step 2.
In the datastore and location attributes, pass the information from snapshotLocationsList in Step 3.
In the esxHostName attribute, pass the information from availableEsxHostsList in Step 4.

To unmount datastores, follow this workflow:

Step REST API Comments

Step	REST API	Comments
1	`/4.1/datastores/backups/ {backupId}/mounted`	`Get the list of mounted datastores`. Note the datastore moref(s) that you want to unmount.
2	`/4.1/datastores/unmount`	`UnMount datastores for a backup` unmounts the specified datastore backup. Pass the datastore moref(s) from Step 1.

/4.1/datastores/backups/ {backupId}/mounted

Get the list of mounted datastores.
Note the datastore moref(s) that you want to unmount.

/4.1/datastores/unmount

UnMount datastores for a backup unmounts the specified datastore backup.
Pass the datastore moref(s) from Step 1.
