| External device setting changed |
- Either change the settings back to the values used when the volume was mapped, or use Universal Volume Manager software to delete an LU and then add an LU.
- 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.

| Illegal request or 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 TrueCopy, Universal Replicator, ShadowImage, 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.

| Cannot detect port |
- There is a problem
with connection to the external storage system. The possible
causes are:
- Cable connection.
- Port settings. The topology settings of the local storage system port
and the external storage system port might not
match.
- Switch settings. If the external
storage system is connected through switches, make
sure that the switch settings are correct.
Verify whether the cables are connected correctly, and then set the ports correctly.
LUN security might have been enabled. If so, verify whether the LUN security setting is correct.
