7.4.4 Fetching device information from a Storage Server

This process can be executed using either GUI or command operations.
For details on the operation method using the GUI, refer to "View Storage Server Device Information" in the "ETERNUS SF AdvancedCopy Manager GUI User's Guide".

For details on the operation method using commands, refer to stgxfwcmsetdev (Device information collection/reflection command).

Note

  • Device information on the Storage Server must briefly be stored in the repository.
    The area required when updating the repository may not be available when information concerning devices under multiple Storage Servers is fetched. Therefore, check if there is sufficient area for updating the repository before fetching the device information. If there is insufficient area, allocate the required area before fetching the device information.

    Refer to the edition of the following manual that is applicable to the OS of the Storage Management Server for the procedure:

    • Step 2, "Response to repository access failure" in "ETERNUS SF AdvancedCopy Manager Operation Manual".

  • The time required for this operation depends on the total number of devices defined on the Storage Server. If the number of devices is large, perform this operation while the CPU load and I/O load are both low. As a guideline, each operation takes about 0.5 seconds per device (or partition) under no-load conditions.

  • When backup synchronous processing or synchronous replication processing is being performed, device information may not be obtained accurately. Therefore, when determining device information, please take this into consideration when synchronous processes are canceled.
