Figure. Hitachi Block Device Wizard - Select proxy node
| Control | Description |
|---|---|
| Proxy Node | Select a Protector node to act as a proxy. CAUTION: ISM nodes and
their associated CMDs used to control storage devices must not be shared with applications
other than those forming part of the Ops Center suite.
Note: The proxy node is responsible for interfacing with the Block storage device. It can be a Windows or Linux machine with the Protector Client software installed and must be connected via a command device to the Block storage device. The command device must only have user authentication enabled. The proxy node must have supported version of CCI installed. Refer to the Command Control Interface documentation available at https://knowledge.hitachivantara.com.

Note: This screen is only displayed during node creation, it is not displayed in edit mode.
Figure. Hitachi Block Device Wizard - Specify Device
| Control | Description |
|---|---|
| Select from detected storage devices | Select this option to specify the hardware storage device by serial number. A list of storage device serial numbers, available to the proxy node selected in the previous step, is displayed in the dropdown menu below. |
| Specify by IP or Hostname with a port | Select this option to specify the hardware storage device using the IP address or hostname and port number of an IP command device on the storage device. Additional In-band and Out-of-band command devices can be added at a step later in the wizard. Note:
For HUS VM storage devices, use the IP address of the SVP. For VSP G1x00 storage devices, use the IP address of CTL1 or CTL2. DO NOT use the IP address of the SVP. When performance is important or where high workloads are expected, the use of In-band Channel command devices is highly recommended. Using Out-of-band command devices will result in slower performance. |
Figure. Hitachi Block Device Wizard - Specify credentials for device
| Control | Description |
|---|---|
| Storage Device Serial Number | Displays the serial number of the Block device specified in the previous step. Note: When the serial number is displayed it is the serial number as provided by CCI, as such the serial number for the VSP 5000 series will have a “5” added to the beginning. Whereas the serial number for the VSP G1x00 and VSP F1500 will have a 3 added to the beginning.
|
| Username | Enter the username for the Block device. Note: The username specified must be a member of the Storage Administrator (Provisioning, Local Copy, Remote Copy) and Security Administrator (View Only, View and Modify) on the Block device. In addition, the Support Personnel role is required for changing the Array SOM settings that allow LDEV resizing for replications. If the Block device cannot be accessed or its credentials are invalid then the node will fail authorization. The configuration wizard can be reopened to correct any errors.
|
| Password | Enter the password for the Block device. Note: The password for authorizing a Block device must contain only useable CCI command characters: A-Za-z0-9’-./:@\_

Figure. Hitachi Block Device Wizard - Specify Configuration for GRR
| Control | Description |
|---|---|
| Enable | Allows the configuration of the Global Replication Roprts to be filled out. Note: GRR functionality uses certain CM-REST APIs which may require this array to be linked to an SVP. (Please see the CM-REST documentation for more information.) Full list of commands used can be found here Commands used to generate GRR
|
| CM-REST Server Address | Enter either the Host Name or the IP Address of the CM-REST server. |
| Port Number | Enter the port number for the CM-REST server. |
| HTTPS | Select to enable secure communications to the CM-REST server. |
| Ignore SSL certificate errors | Select to ignore SSL certificate errors when communicating with the CM-REST server. |
| Username and Password | Enter the username and password for the storage array. Note: If CM-REST is on the same server as the Block Device Node then the credentials must be different.
|
| Refresh Interval | Enter the required interval between refreshes of the GRR reports. Note: Populating the data in the GRR reports requires interaction with the storage array and therefore on busy systems it is not recommended to have short refresh times as this may affect performance of the system.
|
Figure. Hitachi Block Device Wizard - Specify LDEV Provisioning Range
| Control | Description |
|---|---|
| All | Select this option if you want Protector to automatically detect the LDEV range from which snapshots and replications should be allocated. |
| User defined | Select this option if you want to manually specify the LDEV range from which snapshots and replications should be allocated. Note:
All replication and snapshot S-VOLs must be created using free LDEV IDs that are mapped to the meta_resource group, and have virtual LDEV IDs matching their corresponding physical LDEV IDs. For fully provisioned snapshots and all replications, this applies to the operation that creates that snapshot or replication. For floating device snapshots and snapshots mounted using cascade mode, this applies to the mount or restore operation. For fully provisioned snapshots mounted using cascade mode, this applies both to the operation that creates that snapshot and to the mount or restore operation. If an operation tries to create one or more LDEVs, that operation will fail if there are not enough free LDEV IDs that meet the above conditions. |
| Start | Enabled only if User defined is selected. Enter the lower limit of the LDEV range to use for allocation. |
| End | Enabled only if User defined is selected. Enter the upper limit of the LDEV range to use for allocation. |
Figure. Hitachi Block Device Wizard - Command Device Specification and Priority
The user able to specify zero or more In-band or Out-of-band command devices in priority order.
If no command devices are specified, then Protector will attempt to control the hardware storage device via any connected command device, available to the Proxy Node specified, in an order specified by HORCM.
If one or more command devices are specified, then Protector will attempt to control the hardware storage device via a command device in the order specified by the user. If the first command device fails, Protector will progress to the next. If all specified command devices fail then the operation fails. Protector will not attempt to use any command devices that are not specified, even if they are available.
for example, it is possible to specify a specific In-band command device, followed by any In-band command device, followed by a specific Out-of-band command device.
| Control | Description |

| Port Number | Enter the port number of the command device. |
Figure. Hitachi Block Wizard - Specify LDEV Ranges for each VSM
Note: GAD replications require P-VOLs and S-VOLs to have matching virtual serial numbers and virtual LDEV IDs. To avoid virtual LDEV ID collisions between GAD volumes and non-GAD S-VOLs (created by Protector for other types of replications and snapshots), it is possible to define virtual LDEV ID ranges to be used by those non-GAD operations. Virtual LDEV ranges can be specified for each VSM (Virtual Storage Machine) to be used.
| Control | Description |
|---|---|
| Edit |
Enabled only if one Virtual LDEV range is selected. The Configure Virtual LDEV Range page of the wizard (see below) is displayed to enable a port to be added. |
| Delete |
Enabled only if one or more Virtual LDEV ranges are selected. Deletes the Virtual LDEV range(s) from the list. |

| Virtual Serial(s) | The Virtual Serial(s) and associated LDEV Ranges that will be used. |
Figure. Hitachi Block Wizard - Configure Virtual LDEV Range
CAUTION:
These ranges are used to control the virtual LDEV IDs used for non-GAD replications and snapshots. They must be defined to exclude the IDs of any GAD volumes. Failure to provide such a range (or providing an incorrect range) may result in ID clashes when attempting to set up GAD replications.
| Control | Description |
|---|---|
| VSM Serial Number | Enter the serial number of the VSM you intend to use within Protector. |
| Start of LDEV range | Enter the lower limit of the LDEV range to use for allocation. |
