Chapter 9 Connectivity Management
9.2 Functions in the Action Area for Connectivity
•
Asymmetric / Symmetric Logical Unit Access
Select the access type from the host to a volume.
-
ACTIVE-ACTIVE / PREFERRED_PATH (Default)
When multiple paths are used for connection between the host and the ETERNUS
DX Disk storage system, there are recommended paths and non-recommended
paths. While the volume can be accessed by using either types of paths, if a non-
recommended path is used, the responses to the host may require a longer period
of time.
-
ACTIVE / ACTIVE
When multiple paths are used for connection between the host and the ETERNUS
DX Disk storage system, any paths can be used equally.
When ETERNUS Multipath Driver is used, the "Asymmetric/Symmetric Logical Unit
Access" setting is disabled. This setting value is available for multipath drivers, such as
Oracle/Sun standard multipath drivers or the Solaris 10 Leadville environment which
can control multipath operations between the device and the server with commands.
•

-
No Conversion (Default)

To SK/ASC/ASCQ
Customize sense data conversion.
Click the [Add] button. Enter SK/ASC/ASCQ of the conversion target in the "From"
field, and SK/ASC/ASCQ of the conversion destination in the "To" field.
"From SK/ASC/ASCQ" and "To SK/ASC/ASCQ" values are specified in pairs. The
corresponding "From SK/ASC/ASCQ" sense data is changed to the specified "To
SK/ASC/ASCQ" value.
"*" indicates a wild-card, and targets all values.
The maximum number of sense data conversions is eight patterns.
Sense Key (SK): SK indicates sense keys included in the sense information.
Additional Sense Code (ASC): ASC indicates sense codes included in the sense
information.
Additional Sense Code Qualifier (ASCQ): ASCQ indicates additional sense code
qualifier included in the sense information.
[Example 1]
The sense information (4/f1/0) is converted to (4/f1/1) before responding to the
host.
From SK/ASC/ASCQ: 4/f1/0
To SK/ASC/ASCQ: 4/f1/1
[Example 2]
The sense information (4/f1/0 - ff) is converted to (6/f1/0 - ff) before responding
to the host.
"*" indicates all patterns from "0" to "ff". The "*" part is not converted.
From SK/ASC/ASCQ: 4/f1/*
To SK/ASC/ASCQ: 6/f1/*
