To create logical devices (LDEVs) on a Hitachi array

1. In the Tools section of the Console, click LUN Builder.

2. In the LUN Builder's Select Array panel, do the following and click Next:

In the drop-down list, click the name of a Hitachi array that supports LDEVs.

Click LDEV.

3. In the LDEV Creation Options panel, select a RAID group from which to create the LDEVs.

The RAID group must have free capacity greater than or equal to the product of the LDEV size and number of LDEVs you are creating.

4. Complete the rest of the fields in the LDEV Creation Options panel as follows. Then click Next.

Type a number in the Number of LDEVs field to specify how many LDEVs you are creating.

For Tagma and 9900 series arrays, click a value in the Emulation Mode drop-down list to select an emulation mode; for example, OPEN-3 or OPEN-8. The maximum LDEV size for the selected emulation mode is displayed below the drop-down list.

For other Hitachi arrays, click a value in the Bind LDEV to Storage Processor field to specify the array processor to which the new LDEVs will be bound.

In the LDEV Size field, specify a size in gigabytes (GB). Each LDEV you create will have this size.

5. In the Summary panel, do the following:

Verify that your selections are correct.

To defer the task until later, check Schedule Task and use the drop-down lists to specify a date and time. (Time is in 24-hour format; for example, 21:00 means 9:00 p.m.)

To submit the task immediately, clear Schedule Task.

Click Finish to confirm your selections and create the LDEV, or click Back to go back and make changes.

Your LUN creation request is submitted as a task to CommandCentral Storage.

6. After you create LDEV LUNs, you can use them to build aggregate LUSEs,

Creating Hitachi LUSE aggregate LUNs

Use the following procedure to create LUSE aggregate LUNs on a Hitachi array.

To create an aggregate LUSE on a Hitachi array

1. In the Tools section of the Console, click LUN Builder.

2. In the LUN Builder's Select Array panel, do the following and click Next:

In the drop-down list, click the name of a Hitachi array that supports LUSE LUNs.

Click LUSE.

3. In the Select LDEVs for LUSE panel, do the following and click Next:

Click a value in the Group drop-down list to select a RAID level. This setting determines the LDEVs available to you and also determines the size of the new LUSE LUN.

Accept the value of Concatenate. This indicates the layout of the LUN.

In the table, check two or more LDEVs that will be combined into the new LUSE LUN.

As you select LDEVs, the Selected Capacity field is updated to show the total capacity of the new LUN.

4. For Hitachi array types other than 9910 and 9960 Series, skip to step 5.

For 9910 and 9960 Series arrays, all LUSE LUNs must be bound to a host storage domain (array virtual port). Use the Select Host Storage Domain panel to create port bindings for the new LUN. Do the following and click Next:

In the list, click the host storage domain to which the LUN will be bound.

In the SCSI LUN ID field, type an ID by which the LUN will be known to the port.

5. In the Summary panel, do the following:

Verify that your selections are correct.



Click Finish to confirm your selections and create the aggregate LUSE, or click Back to go back and make changes.

Your request to create a LUSE LUN is submitted as a task to CommandCentral Storage.

To create a LDEV (an unmapped LUN) (ONLY a basic guide):

1. Connect to storage navigator (http://IPADDRESSofSVP2. Select the array and Login3. One your logged in, click the pen in the top right hand corner to change to modify mode4. Click on the LUSE/VLL icon on the left hand side (its the one what looks like a disk with a spanner)5. Click the VLL tab6. Expand the box number you want to create LDEV in7. Expand the parity group (RAID Group) (the blue icon) you want to create the LDEV in 8. Select the VDEV (the red icon you want to create the LDEV in9. right mouse click on free space10. Select install CV 11. Follow the wizard to create a new LDEV/LDEV (if your connect to an open system (not a mainframe), the emulation type will be Open-V)

Once you created and formatted the LDEV, you can map it using LUN manager ONLY a basic guide):

(NOTE: This process requires that zoning is already completed)

1. Click the LUN manager ICON (the icon that looks like a disk with a key)2. expand a port to present the LUN down3. If required create a host group by right mouse clicking the port (or use the default one if not required)4. Set the Host type and WWN5. Select the host group6. In the LDEV window, select the LDEV you want to map (the one you created above)7. Select the H-LUN number in the LUN path (using the top box on the right hand side)8. Click "add LUN path"9. Click ok

You can also do the provisioning task with Device manager, the process is dependent on the version you are running.

To create a LUN you should do the following process:

Connect to storage navigator Select the array you think which is suitable and Login After you are logged in. click the pen in the top right hand corner and change the

modify mode Click on the LUSE/VLL icon and Click on the VLL tab Gradually expand the box number you want to create LUN Expand the parity group you want to create the LDEV Select the VDEV and right click on free space and Select install CV create a new LDEV/LDEV by following the wizard If your connected to an open system then emulation type will be Open-V

After creating and formatting the LDEV, you should map it using LUN manager as follows:

Click on the LUN manager ICON Eventually expand a port to bring the LUN down Right click on the port and create a host group and set Host type Select the LUN you want to map through the LUN window Select and add the H-LUN number in the LUN path, then click ok

Masking array storage to host ports using the LUN Masking wizard

You can mask host ports to array LUNs using the LUN Masking wizard. Launch the dialog from the object view for either a storage object (such as an array or LUN) or a host (such as a host, HBA, or HBA port).

To mask array storage to a host port

1. In the Console, display the object view for a storage object (such as an array or a LUN) or for a host object (such as a host, HBA, or HBA port).

2. In the drop-down list, click Add LUN Masking(s) and click Go to launch the LUN Masking wizard.

3. If you launched the wizard from a storage object, skip to step 4.

If you launched the wizard from a host object, choose an array by clicking its name in the Select Array window's drop-down list. Then click Next.

4. If the array does not require an array port to be specified as part of the masking operation, skip to step 5.

Otherwise, click an array port in the Select Array Port window's drop-down list and then click Next.

5. In the Add LUN Masking(s) panel, which lists all permissible combinations of storage and the hosts that can consume the storage, do the following:

Check one or more storage-host combinations in the table. LUN masking will occur for each combination you select.



Click Finish.

The LUN masking operation is submitted as a task to CommandCentral Storage. In the array object view, the LUNs involved in the masking operation are displayed in a Task Reserved table until the operation is completed.

Creating zones

Use the Zone Builder to create zones and manage them.

Note:

Prior to CommandCentral Storage 5.1.1, the objects in a zone could not come from more than one fabric. That restriction no longer applies.

To create a zone

1. In the Tools section of the Console, click Zone Builder.

2. In the Zone Builder's Select Fabric and Zone panel, do the following and click Next:

In the Fabric drop-down list, click the SAN fabric on which you want to create the new zone.

In the Switch drop-down list, click a switch within the fabric.

Click Create New.

In the Zone field, type the zone name.

Zone names must consist of alphanumeric characters and/or the underscore (_) mark. Spaces, punctuation marks, and special characters are not valid.

If you want the new zone to draw its members from more than one fabric, check Enable zone member selection from multiple fabrics.

3. In the Modify Members panel, do the following and click Next:

Check one or more objects in the Available Objects list. (You can expand an object's branches and sub-branches to display individual nodes and ports.)

Checked objects are added to the Zoned Objects table on the right side of the panel.

To remove objects from the zone, check their names in the Zoned Objects table. Then click Remove Object(s) and click Go.

4. In the Modify Zone Set Membership panel, which displays only if the fabric on which you are updating the zone supports zone sets, do the following and click Next:

Check at least one inactive zone set in which the new zone will be a member.

The new zone will become a member of the zone set when the zone set is enabled.

To enable one of the inactive zone sets you checked, click Enable Zone Set and then click a zone set in the drop-down list.

5. In the Confirm Selections panel, verify that your selections are correct. Then do the following:

For zones on a Cisco fabric, check Save Switch Configuration to save the zone configuration to the switch.

If you do not choose this option, the switch's physical configuration remains unchanged.



Click Next to confirm your selections, or click Back to go back and make changes.

6. In the View Proposed Changes panel, which displays a Topology Map showing the fabric with the proposed zone members highlighted, verify that your selections are correct. Then click Finish to create the new zone or click Back if you need to go back and make changes.

After you click Finish to close the wizard, a request is submitted to create the zone.

Modifying zones

Use the Zone Builder to modify a zone. You can add or remove members, and you can update the list of zone sets to which the zone belongs.

Note:

You cannot modify a zone that belongs to an active zone set. You can, however, modify a defined zone having the same name as the active zone. After you make the changes, they are reflected in the active zone when a user enables a zone set containing the zone.

To change the active status for a zone set,

To modify a zone

1. In the Managing Summary pane, click Zones and Zone Sets.

2. In the Defined Zones table in the Zones Summary, check a zone.

3. In the drop-down list above the table, click Edit Zone and click Go.

4. In the Zone Builder's Select Fabric and Zone panel, do the following and click Next:

Adjust the values for Fabric, Switch, and Zone if necessary.

By default, the Zone Builder uses values for the zone whose object view you were displaying when you launched the Zone Builder.

If you want to modify the zone so that it includes members from more than one fabric, check Enable zone member selection from multiple fabrics.

5. In the Modify Members panel, do the following and click Next:

To add objects to the zone, check their names in the Available Objects list. (You can expand an object's branches and sub-branches to display individual nodes and ports.)


To remove objects from the zone, check their names in the Zoned Objects table. Then click Remove Object(s) and click Go.


Check inactive zone sets in which you want the zone to be a member.

The new zone will become a member of the selected zone sets when they are enabled.

To enable one of the inactive zone sets you selected, check Enable Zone Set and then click a zone set in the drop-down list.



If you do not choose this option, the switch's physical configuration remains unchanged. Your updates are reflected in the CommandCentral Storage database only until the next time the switch is discovered.





After you click Finish to close the wizard, a request is submitted to modify the zone.

To add an object to a zone

1. In the Managing section of the Console, display the object view for an object that can be a member of a zone, such as host or an array.

2. In the drop-down list, click Add to Zone and click Go.

3. In the Zone Builder's Select Fabric and Zone panel, click values for Fabric, Switch, and Zone to identify the zone to which you are adding the object. Then click Next.

4. In the Modify Members panel, add objects to the zone by checking their names in the Available Objects list. (You can expand an object's branches and sub-branches to display individual nodes and ports.) Then click Next.



Click inactive zone sets in which you want the zone to be a member.





If you do not choose this option, the switch's physical configuration remains unchanged. Your updates are reflected in the CommandCentral Storage database only until the next time the port bundle is discovered.






To remove an object from a zone

1. In the Managing section of the Console, display the object view for an object that is a member of a zone.

2. In the drop-down list, click Remove from Zone and click Go.

3. In the Zone Builder's Select Fabric and Zone panel, click values for Fabric, Switch, and Zone to identify the zone from which you are removing the object. Then click Next.
