Adding a New Logical Drive or Adding a Logical Volume From New Logical Drives

Use this option to add one or more new logical drives to an existing configuration of RAID sets or to add a logical volume from new logical drives. To add a logical volume from existing logical drives, see Adding a Logical Volume From Existing Logical Drives.

NOTE: Logical volumes are unsuited to some modern configurations such as Sun Cluster environments, and do not work in those configurations. Use logical drives instead.

NOTE: On systems running Solaris, if the logical drive is going to be larger than 253 Gbyte, see Preparing for Logical Drives Larger Than 253 Gbyte.

  1. Select the appropriate array.
  2. Select Configuration > Custom Configure.
  3. NOTE: This selection is inactive unless you have selected a controller with available physical drives.

  4. Select Add LDs/LVs to the Current Configuration from the Custom Configuration Options window.

  5. Verify the server and controller that are displayed at the top of the window are correct.

  6. Select a disk you want to be included in the new logical drive and click Add Disk.
  7. If you make a mistake or change your mind, select the drive in the participating drives list and click Remove Disk.

  8. Select a RAID level. For definitions of the RAID levels, see RAID Levels.

  9. Select the desired Host channel and SCSI ID to which you would like your new logical drive to be mapped to from the Channel and the SCSI ID list boxes.
  10. Set the Max Drive Size. The Max Drive Size displays the total capacity of each disk. A smaller logical drive can be created by decreasing this value.

    NOTE: If you do not change the Max Drive Size but you do change the Partition Size, SANscape creates a new partition at the specified partition size. Remaining capacity can be used later by expanding the drive (as explained in Expanding the Capacity of a Logical Drive). The drive capacity is no longer editable after a partition is created.

    NOTE: If you want to create another logical drive on the same controller, click New Logical Drive. SANscape creates the logical drive you just defined and returns to the top of the window, enabling you to create another logical drive. On a SANnet II 200 SCSI array, you can create up to eight logical drives with up to 32 partitions per logical drive. On a SANnet II 100 Blade SCSI array, you can create up to six logical drives with up to 32 partitions per logical drive. On a SANnet II 200 FC array, you can create up to eight logical drives with up to 128 partitions per logical drive.

  11. To add this logical drive to a logical volume, click New LD and see Adding a Logical Drive to a Logical Volume.

  12. When you are satisfied with the selections on this window, and do not want to define another logical drive, click Commit. A confirmation window is displayed showing the new configuration.
  13. Click OK to accept the configuration or Cancel to return to the console
  14. NOTE: You cannot change a logical drive configuration after you click OK.

    NOTE: During initialization LD/LV size is displayed as 0 Mbyte.

  15. (HP-UX OS only). To ensure the environment is stable and accurate after making configuration changes, you need to run the ioscan -fnC disk command.

    NOTE: If you used System Administrator Manager (sam) to unmount the file system, make sure it is closed before running the ioscan command.

  16. (IBM AIX OS only). To ensure the environment is stable and accurate after making configuration changes, you need to update the Object Data Manager (ODM) as explained in Updating the Object Data Manager.
