B.3.2.2 When using SynfinityDisk/GDS4.1A20 or earlier

When using SynfinityDisk/GDS, you have to use one of the following two types of disk unmount operations before starting replacement using the menu item "Preventive Maintenance of the Hard Disk Drive (Hot Swap)".

• Manual unmounting using the SynfinityDisk/GDS GUI menu
  This function is triggered by selecting "Swap Physical Disk" from the SynfinityDisk/GDS GUI menu. The function executes unmounting from SynfinityDisk/GDS, and notifies Machine Administration.

  

  In this case, electrical disconnection is performed by the Machine Administration menu operation executed during replacement.

• Manual unmounting using the SynfinityDisk/GDS sdxswap command
  You can use sdxswap to perform logical unmounting. For the sdxswap command arguments, specify the class name and SDX disk name used by SynfinityDisk/GDS.
  For more information, refer to the "SynfinityDisk Handbook" or "PRIMECLUSTER Global Disk Services Handbook."

  # /usr/sbin/sdxswap -O -c <class name> -d <SDX disk name>

  In addition, you have to notify Machine Administration using the diskswap command. For the diskswap command argument, specify the logical device path of slice No. 0 of the relevant disk.

  # /usr/sbin/FJSVmadm/diskswap add <logical device path>

  In this case, electrical disconnection is performed by the Machine Administration menu operation executed during replacement.
