VSP G200, G/F400, G/F600, G/F800 troubleshooting

• LU path settings might have been changed. If this happens, either:
  • Change the settings back to the values used when the volume was mapped.
  • Use Universal Volume Manager software to delete the LU, and then add it again.
• The access attribute of the volume might have been changed by Data Retention Utility. If the volume is protected by the access attribute, release the protection.

Response error

• If the volume is a pair volume, it might be protected because of the pair status. If this is the case, change the pair status or delete the pair. Make sure the volume is not set to a pair such as ShadowImage, TrueCopy, Universal Replicator, or global-active device.
• The access attribute of the volume might have been changed by Data Retention Utility. If the volume is protected by the access attribute, release the protection.

• There is a problem with connection to the external storage system. The possible causes are:
  • Cable connection. Make sure the cable is connected correctly.
  • Port settings. The topology settings of the local storage system port and the external storage system port might not match. Make sure that the ports are set properly.
  • Switch settings. If the external storage system is connected through switches, make sure that the switch settings are correct.

    Make sure the cables are connected correctly, and then set the ports properly.

• LUN security might have been enabled. If so, check whether the LUN security setting is correct.
