Table 38 Path status and examples of recovery procedure (P9500 Disk Array)

Examples of Recovery ProcedurePath 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.
