External device setting changed
|
- LU path settings can be changed by using
LUN Manager. Either change the settings back to the values used when the volume was mapped, or use
Universal Volume Manager software to delete LU and then add 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,
Thin Image, 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. Make sure the cable is connected correctly.
- Port settings. The topology settings of the external port and the target port might not match. Use
LUN Manager to 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.
- LUN security might have been enabled by using
LUN Manager. If so, check whether the LUN security setting is correct.
