Allocating Storage Resources of the Disk Array

Allocating Storage Resources of the Disk Array

When allocating storage resources, you'd better assign all space of a disk domain to a storage pool and assign all space of a storage pool to a LUN.

Creating a Disk Domain

A disk domain is a series of the same or different disks. Before allocating storage resources, you must create disk domains. This section describes how to create a disk domain.

Prerequisites
  • A disk array has been correctly installed and connected with cables.
  • The DeviceManager can be used to access and configure the disk array.
Context

To maximize disk space usage, you are advised to create a disk domain for every 24 disks. If less than 24 disks are left, assign them to one disk domain.

Procedure
  1. Access https://disk-array-management-interface-ip-address:8088 on a browser.
  2. Enter the user name and password and click Log In. The default user name is admin, and the default password is Admin@storage.
  3. Click on the right of the page.
  4. Click in the upper process instruction.
  5. Select Manually select and click Select following the option.
  6. In the Select Disk window, select disks from the left side and click .

    After all disks to be added are displayed in the Selected Disks area, click OK.

    NOTE:

    To maximize disk space usage, you are advised to create a disk domain for every 24 disks. If less than 24 disks are left, assign them to one disk domain. The figure is only an example, and the parameter values are not recommended.

  7. Return to the Create Disk Domain page and click OK.

  8. After a message is displayed, indicating that the disk domain is successfully created, click OK.

Creating a Storage Pool

This section describes how to create a storage pool in a disk domain.

Prerequisites
  • A disk array has been correctly installed and connected with cables.
  • The DeviceManager can be used to access and configure the disk array.
  • A disk domain has been created.
Context
  • You are advised to configure all space of the disk domain as one storage pool.
  • When configuring a RAID policy for the storage pool, the system displays a message, indicating whether the current number of disks supports this RAID policy. If disks are sufficient, RAID6 with the "9D+2P" RAID policy is recommended. If disks are insufficient, the default recommended RAID6 policy is recommended.
Procedure
  1. Access https://disk-array-management-interface-ip-address:8088 on a browser.
  2. Enter the user name and password and click Log In. The default user name is admin, and the default password is Admin@storage.
  3. Click on the right of the page.
  4. Click in the upper process instruction.
  5. In Disk Domain, select the created disk domain.

    In Storage Medium, set RAID Policy to RAID6, select More from the drop-down list on the right side, and select 9D+2P.

    As one storage pool is created for one disk domain, enter the maximum integer indicated by Available Capacity in the Capacity field.

  6. Click OK.
  7. After a message is displayed, indicating that the storage pool is successfully created, click Close.

Creating LUNs and LUN Groups

The LUN size indicates the storage resource size of a disk array recognized by a server. A LUN group is a logical unit for mappings between the disk array and hosts. This section describes how to create LUNs and LUN groups.

Prerequisites
  • A disk array has been correctly installed and connected with cables.
  • The DeviceManager can be used to access and configure the disk array.
  • A storage pool has been created.
Context
  • For how many LUNs a disk array needs to be divided to and how large each LUN is, see Selecting a Deployment Mode.
  • You are advised to group an entire storage pool into one LUN.
  • You must create LUNs and then LUN groups.
Procedure
  1. Access https://disk-array-management-interface-ip-address:8088 on a browser.
  2. Enter the user name and password and click Log In. The default user name is admin, and the default password is Admin@storage.
  3. Click on the right of the page.
  4. Click in the upper process instruction.
  5. Select Use all the available capacity of the owning storage pool for Capacity.

    Select the newly created storage pool from the Owning Storage Pool drop-down list.

  6. Click OK.
  7. After a message is displayed, indicating that the LUN is successfully created, click Close.
  8. Repeat the preceding steps to create the rest LUNs.
  9. Return to the Provisioning page and click in the upper process instruction.
  10. Select LUNs to be added to a LUN group from the Available LUNs area and click .

    After all LUNs to be added are displayed in the Selected LUNs area, click OK.

  11. After a message is displayed, indicating that the LUN group is successfully created, click Close.
  12. Repeat the preceding steps until all LUNs are added to LUN groups.

Creating Hosts and Host Groups

This section describes how to create hosts and host groups.

Prerequisites
  • A disk array has been correctly installed and connected with cables.
  • The DeviceManager can be used to access and configure the disk array.
  • The ID of the FC initiator corresponding to each server has been recorded.
Context
  • If you want to mount disks for a single host, add only the host to a host group.
  • If you want to mount one disk to multiple hosts (such as in HA scenarios), add the hosts to one host group.
  • You must create hosts and then host groups.
Procedure
  1. Access https://disk-array-management-interface-ip-address:8088 on a browser.
  2. Enter the user name and password and click Log In. The default user name is admin, and the default password is Admin@storage.
  3. Click on the right of the page.
  4. Click in the upper process instruction.
  5. Set a host name, select an operating system, enter the host's IP address, and click Next.

  6. In the Configure Initiator window, set Initiator Type to FC for Available Initiators. The FC initiator information about the host will be displayed in the list. Compare the displayed and recorded FC initiator IDs and ensure that they are the same.

    Select the initiator to be added and click .

    After all initiators to be added are displayed in the Selected Initiators area, click Next.

  7. Confirm the host information in the Summary window. If the information is correct, click Finish.
  8. In the warning page, select I have read and understood the consequences associated with performing this operation and click OK.
  9. After a message is displayed, indicating that the host is successfully created, click Close.
  10. Repeat the preceding steps to create the rest hosts.
  11. Return to the Provisioning page and click in the upper process instruction.
  12. Select hosts to be added to a host group from the Available hosts area and click .

    After all hosts to be added are displayed in the Selected Hosts area, click OK.

  13. After a message is displayed, indicating that the host group is successfully created, click Close.
  14. Repeat the preceding steps until all hosts are added to host groups.

Checking the Connection Status of the FC Port

This section describes how to check the connection status of the FC port.

Procedure
  1. Access https://disk-array-management-interface-ip-address:8088 on a browser.
  2. Enter the user name and password and click Log In. The default user name is admin, and the default password is Admin@storage.
  3. Click on the right of the page.
  4. Click Host in the Block Storage Service area.
  5. Select a created host on the Host tab.
  6. The Initiator tab displays the FC port status of the host.

    • If the FC port is in the Online state, it is normally connected.
    • If the FC port is in the Offline state, check whether the disk array and server are properly connected, whether the server works normally, whether the server's HBA card is properly started, and whether the FC port on the disk array is in the normal state. If there is a fault, rectify the fault and check again.

  7. Click on the right of the page.
  8. Click Port in the Storage Configuration and Optimization area.
  9. Click the FC Ports tab.
  10. Check the status of the FC ports connecting to the server.

    • If the FC ports are in the Link up state, they are normally connected.
    • If any FC port is in the Link down state, check the health status of the FC port.
      • If the FC port health state is Normal, check whether the disk array and server are properly connected, whether the server works normally, and whether the server's HBA card is properly started. If there is a fault, rectify the fault and check again.
      • If the FC port is unhealthy, perform troubleshooting according to the disk array product documentation.
