Notes When Power Saving Feature is Used (For TagmaStore AMS Subsystem,
TagmaStore WMS Subsystem)
When the external disk array is TagmaStore AMS2500, AMS2300, or AMS2100 and the power
saving feature is used, do not access the external volume which is spinning down from the host.
When you access the external volume which is spinning down from the host, the state of the external
volume becomes Blockade.
When the state of the external volume becomes Blockade, the external volume will recover
automatically in several hours. The external volume can be recovered manually by executing the
Check Paths & Restore Vol. command.
Connecting VSP Subsystem
When you connect a VSP subsystem as the external subsystem, the local TagmaStore USP microcode
version must be 50-09-98-00/01 or higher. If the local TagmaStore USP microcode version is less
than 50-09-98-00/01, you cannot connect a VSP subsystem as the external subsystem.
When you connect an VSP subsystem as the external subsystem, you need to set the port to the
host group for the Windows hosts (host mode 0C: Windows, host mode 2C: Windows Extension).
Also, the port attribute must be the target port or the RCU target port.
Path Status and Examples of Recovery Procedure (For VSP Subsystem)
Table 20 shows the examples of the recovery procedure when the path status is not normal. When
the path status is not normal, see the troubleshooting of Universal Volume Manager and this table
to recover the path status. If you cannot restore the path, please call the Support Center.
Table 20 Path Status and Examples of Recovery Procedure (For VSP Subsystem)
Examples of Recovery Procedure Path Status
Settings of the LU paths may have been changed by LUN
Manager. External device setting changed
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.
The volume may have been set as a pair volume for data
copy. Check if the volume is set as a pair volume of Illegal request
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
The volume may have been set as a pair volume for data
copy. Response error
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.
