Table 38 Path status and examples of recovery procedure (P9500 Disk Array)
Examples of Recovery Procedure Path Status
Settings of the LU paths may have been changed by LUN
Manager. Check the settings of the LU paths. If the settings
of the LU paths have been changed, change the settings
back to the ones when the volume is mapped. Or use
Universal Volume Manager to perform the Delete Volume
operation and perform the Add Volume operation again.
The access attribute of the volume may have been changed
by Data Retention Utility. Check the access attribute of the
volume. If the volume is protected by the access attribute,
release the protection.
External device setting changed
The volume may have been set as a pair volume for data
copy. Check if the volume is set as a pair volume of
ShadowImage, TrueCopy, Universal Replicator or some
other copy program. If the volume is set as a pair volume,
the volume may be protected because of the pair status.
When the volume is protected, change the pair status or
delete the pair.
The access attribute of the volume may have been changed
by Data Retention Utility. Check the access attribute of the
volume. If the volume is protected by the access attribute,
release the protection.
Illegal request or Response error
There is a problem with connection to the external storage
system. The possible causes are:
• The fibre cable is not physically connected in the proper
way.
•
The setting of the topology does not match between the
external port and the target port.
• If the external storage system is connected through
switches, the settings for the switches may not be
appropriate.
Make sure that the fibre cable is connected properly, and
then set the fibre channel port properly using LUN
Manager.
The LUN security may have been enabled by LUN
Manager. Check if the LUN security is enabled or not. If
the LUN security is enabled, disable the LUN security.
Cannot detect port
Notes on Using the Power Savings Option (AMS/WMS)
When the AMS 2500, AMS 2300 or AMS 2100 storage system is connected as an external
storage system and the Power Savings option is enabled on the external storage system, do not
access external volumes from a host if the external volumes are spinning down. If an external
volume is accessed from a host when the external volume is spinning down, the status of the external
volume changes to Blockade.
If the status of the external volume changes to Blockade, the external volume will be automatically
restored in several hours. You can also manually restore the external volumes by using the Check
Paths & Restore Volume command.
