Use the following procedure when creating FlashCopy logical drives on a host running NetWare 5.1 (or higher). Failure to complete the steps listed may result in an inaccurate point-in-time image of the base logical drive.
For a process overview of the FlashCopy logical drive creation process, refer to Create FlashCopy Logical Drive Wizard: Process Overview - NetWare.
FlashCopy logical drives may be reused (for frequent or nightly backups) or may be created for one-time usage (speculative change or upgrade testing). For instructions on how to reuse a disabled FlashCopy logical drive, see Reusing FlashCopy Logical Drives.
Caution: The following restriction applies when attempting to create FlashCopy logical drives on NetWare:
FlashCopy logical drives on NetWare may not be mapped on the same host as the base logical drives.

Start the storage management software. Result: The Enterprise Management Window is displayed. |
||||||||||||
2 |
Launch an Subsystem Management Window using one of the following methods:
Result: The Subsystem Management Window is opened in a separate window. |
||||||||||||
3 |
Within the Logical pane of the Subsystem Management Window, select a standard logical drive
|

4 |
Press Ctrl + Esc and select Server Console. Result: The server console prompt is displayed. |

5 |
If supported by the operating system, run the hot_add Once logical drives have been created and logical drive-to-LUN mappings have been defined, the hot_add utility is run to ensure that the operating system is aware of the newly created logical drives, without having to reboot the host. For information on which operating systems support the hot_add utility, refer to the Storage Manager Software Installation Guide. |

Important: FlashCopy logical drives on NetWare may not be mapped on the same host as the base logical drive. Complete the following steps to mount the FlashCopy logical drive to its intended host.
|
||||||||||||
|
Important: All I/O activity to the base logical drive should be stopped at this point (or data transfer suspended). This will ensure that an accurate point-in-time image of the base logical drive is captured. |
||||||||||||
7 |
Complete the following steps to dismount the base logical drive.
|

8 |
In the storage management software, re-create the FlashCopy logical drive using one of the following methods:
|
||||||||||||
9 |
Return to the server console and remount the base logical drive. |
||||||||||||
10 |
Exit all applications and reboot the host operating system. |
||||||||||||
|
Important: If I/O activity to the base logical drive was stopped or data transfer was suspended, resume I/O activity to the base logical drive at this time (or re-enable data transfer). |

Use the FlashCopy logical drive in conjunction with your backup application (reuse of FlashCopy logical drive) or for speculative change and upgrade testing (one-time usage). For information on reusing a disabled FlashCopy logical drive, see Reusing FlashCopy Logical Drives. |

Once the FlashCopy logical drive is no longer required, disable or delete the FlashCopy logical drive. If you disable the FlashCopy logical drive instead of deleting it, you can retain the FlashCopy logical drive and its associated FlashCopy repository logical drive. Then, when you need to create a different FlashCopy of the same base logical drive, you can re-create the disabled FlashCopy logical drive. This takes less time than creating a new FlashCopy logical drive and will stop any reduction in performance that may occur if the FlashCopy logical drive remains available. For more information, see Disabling a FlashCopy Logical Drive or Deleting a Logical Drive. For command reference information on disabling or deleting a FlashCopy logical drive, refer to the Enterprise Management Window online help. |
Typically, once a FlashCopy logical drive has been created it would be disabled until a new point-in-time image of the same base logical drive is required. To create a new point-in-time image of the same base logical drive, complete the following steps.
