Clariion CX, CX3, CX4 – How to add Storage Capacity to Attached Host






Microsoft Windows



1. If needed, add new drives to the storage system.


2. If needed, create a hot spare using Navisphere Manager.


3. If needed, create an additional RAID group on the drives using Navisphere Manager.


4. Create (bind) additional LUNs on the RAID group using Navisphere Manager.


5. Assign the new LUNs to the server using Navisphere Manager.


6. Verify that the new LUNs were assigned to the server using Navisphere Manager.


7. On the server, verify that the server has access to the LUNs:


a. On the Windows desktop, right-click My Computer and click Manage.


b. In the left pane of the Computer Management dialog box, double-click on the storage icon.


c. Click Disk Management.


d. Verify that the LUNs that you added are listed in the right pane.


8. Start or restart the Navisphere Host Agent to push the server’s LUN mapping and operating system information to the storage system.


9. On the server, start PowerPath and verify that PowerPath sees all of the paths to the LUN.



Linux


1. If needed, add new drives to the storage system.


2. If needed, create a hot spare using Navisphere Manager.


3. If needed, create an additional RAID group on the drives using Navisphere Manager.


4. Create (bind) additional LUNs on the RAID group using Navisphere Manager.





5. Assign the new LUNs to the server using Navisphere Manager.


6. Verify that the LUNs were assigned to the server using Navisphere Manager.


7. On the server, verify that all LUNS have entries in the /proc/scsi/scsi/ directory.


8. On the server, verify that each LUN has an entry in the appropriate HBA file:


· For QLogic HBAs, the entry is in proc/scsi/qlaxxx/hba_number


· For Emulex HBAs, the entry is in /proc/scsi/lpfc/hba_number


9. On the server, verify that the failover software recognizes all of the paths to the LUNs.


For example, for PowerPath, verify that PowerPath recognizes all of the paths to the LUNs using the powermt command: powermt display dev=all class=clariion


10. Partition the LUN and then create and mount a file system to make the LUN available to the operating system.


11. Run the Navisphere Host Agent to push the server’s LUN mapping and operating system information to the storage system.


12. Save the failover configuration.


For example, for PowerPath, save the PowerPath configuration using the powermt savecommand.





13. On the server, verify that the server and failover software sees all of the paths to the LUN.V


For example, for PowerPath, verify the configuration using the powermt display command.
