Chapter 4 Operating NEC Storage PathManager

During redundant operation, multiple paths are displayed under each "LogicalUnit." The example above

shows that there are two logical units and two paths in NEC Storage. Refer to "Chapter 3 Functions of NEC

Storage PathManager" for detailed information about the display.

It may take some time (up to a minute) for the spscmd to return its result if the spscmd is used right

after the server starts up. This is because the spscmd waits for WMI to start up, and this is not a failure.

Wait for the spscmd to return the result.

If only one path is displayed in the -getlun option of the spscmd, first refer to "4.2.1 FAQs and

troubleshooting" to see if solutions can be found before making inquiries.

(1) Priority

NEC Storage PathManager determines the initial value of the priority in the following ways.

/1/ When a new path, or a path to a newly recognized logical unit, is found, the path priority becomes

enabled with a priority level of 1.

/2/ When a new path to an already recognized logical unit is found, the priority of the path will become the

highest priority among the paths to the logical unit + 1, and the path priority will become disabled.
