This wizard is displayed when you assign a mount operation to a Hitachi Block storage node on a data flow.
Note:
- When mounting a snapshot that contains a mounted subdirectory, the subdirectory will be mounted as expected. However, the volume referenced by the subdirectory will also be mounted as a separate drive. Unmount will unmount both the expected and additional mounts.
- The automated mount operation is not suitable for Oracle ASM. The disks are be presented to the OS but need to be manually mounted.
Note: Operating system specific behaviour:
| OS | Note |
|---|---|
| Linux | When mounting a Linux snapshot to a different Linux machine; in order for the user and group names to be displayed correctly the users and groups must have the same ID's as the source. |
| SUSE Linux | SUSE Linux is not able to perform automated mount operations if hosted on VMware. (RHEL and OEL Linux work as expected). |
| AIX | The system command importvg is invoked by Protector to mount snapshots to the user specified location. importvg creates a directory for the user specified location plus an empty directory corresponding to the original mount point. Neither of these directories are removed by Protector when the snapshot is eventually unmounted, although neither will contain any data. |
Figure. Mount Configuration Wizard - Mount Operation Type
| Control | Description |
|---|---|
| Repurpose | Perform the mount sequence for the repurposing scenario (refer to About the repurposing mount sequence for details). Note: Repurpose is not valid for continuous replication; the rules compiler will issue an error if a continuous mover is used on the data flow in conjunction with this type of mount operation.
|
| Proxy Backup | Perform the mount sequence for the proxy backup scenario (refer to About the proxy backup mount sequence for details). Note: A proxy backup of a live replication will generate a warning in the compiler to tell the user that their replication will be paused until the proxy backup is complete.

Figure. Mount Configuration Wizard - Mount Level
| Control | Description |
|---|---|
| SAN | Adds the replication to a Host Group. |
| Host | Adds the replication to a Host Group and confirms that it is available from the specified Host. |
| OS | Adds the replication to a Host Group and mounts it on the specified Host's operating system. |

Figure. Mount Configuration Wizard - Select Host Group (SAN level mount only)
| Control | Description |
|---|---|
| Host Group | Manually specify or select a host group to use to expose a snapshot
or replication. Note: When exposing an
LDEV, the host group specified must be in the same resource group as the secondary
volumes.
|
| Add Host Group | Click this button to add host groups when specifying a multi-path mount operation. |

| Previous | Takes the user to the previous screen in the wizard. |
| Finish | Commits the new changes. Pages currently open in other tabs and windows will need to be reloaded before the changes are seen by the user. |
Figure. Mount Configuration Wizard - Host Group (Host
and OS level mount only)
| Control | Description |
|---|---|
| Automatically discover | Protector will automatically select a host group to use to expose the snapshot or replication. |
| Selected | The user must specify one or more host groups to use to expose the snapshot or replication. |
| Select a Host Group | Manually specify or select a host group to use to expose a snapshot
or replication. Note: When exposing an
LDEV, the host group specified must be in the same resource group as the secondary
volumes.
|
| Add Host Group | Click this button to add host groups when specifying a multi-path mount operation. |
| Cancel | Discards all changes and reverts to the previous page. |

Figure. Mount Configuration Wizard - Select Host (Host
and OS level mount only)
| Control | Description |
|---|---|
| OS Host | Specify the machine to mount to or expose to. Note: Unless the user selects a host group, the machine where the volume is to be mounted must have an existing volume on the same storage device. If there is no connection between the mount host and the block storage device then Protector will fail the mount operation after a timeout of 30 minutes.
|
| VMware host | Expose the volumes to the specified VMware host to enable them to be mounted to the VM. Note: Exposing using a VMware host requires that a VMware vCenter node be configured.
|
| Datastore | Specifies a destination datastore when mounting to a VMware virtual machine which is part of a cluster, in which case the default datastore may not be a suitable place to save the RDM mount information. If the datastore field is left blank then mount information is saved alongside the VM. |

Figure. Mount Configuration Wizard - Specify
mount location (OS level mount only)
| Control | Description |
|---|---|
| Original | The replication is mounted at its original location. Note: Mounting at the original location will fail if there is already a volume mounted at that location.
|
| Drive starting at letter | When mounting a replication that contains multiple volumes, the first volume will mount at the specified drive and subsequent drives are used for each additional volume. |
| Directory | When mounting a replication that contains multiple volumes, each volume will be assigned a separate subdirectory. Click Browse to view the drives and directories on the selected host. To create a new directory, type in the required path. Note: Protector does not check to make sure the directory selected as the mount point is empty. This means it is possible to mount a snapshot inside or even over the top of another mounted volume. This should be avoided.
