For HA pairs, you can run the commands from either controller.
4.
Replace SAS cables by completing the following substeps:
You can ignore cabling messages that might appear on the console.
Note: When replacing a SAS cable, wait a minimum of 10 seconds before plugging in the
new cable so that the system can detect the cable change.
Note: Wait at least 10 seconds before connecting the port. The SAS cable connectors are
keyed; when oriented correctly into a SAS port, the connector clicks into place and the disk
shelf SAS port LNK LED illuminates green. For disk shelves, you insert a SAS cable
connector with the pull tab oriented down (on the underside of the connector). For
controllers, the orientation of SAS ports can vary depending on the platform model;
therefore, the correct orientation of the SAS cable connector varies.
a. Replace cables on Side A one cable at a time.
The Side A cables are the cables connected to IOM A of each disk shelf.
b. Verify that you have correctly replaced the SAS cables by entering the following command
at the console of either controller:
sysconfig
The output should be the same as Step 1: the system should be Multi-Path HA or
Multi-Path, and the SAS port and attached disk shelf information should be the same.
If the output is something other than Multi-Path HA or Multi-Path, you must identify
the cabling error, correct it, and run the sysconfig command again.
c. Repeat substeps a and b for Side B.
The Side B cables are the cables connected to IOM B of each disk shelf.
Replacing SAS cables in a single-controller-single-path or single-controller-mixed-path
configuration
You must halt your system before replacing SAS cables in a single-controller-single-path or
single-controller-mixed-path configuration.
Steps
1. Verify that your system configuration is correct:
• For 7-Mode:
sysconfig
• For clustered systems, enter the following command at the clustershell prompt:
run -node nodename|local sysconfig
Note: It might take up to a minute for the system to complete discovery.
Single-Path or Mixed-Path is listed in the
System Storage Configuration
field.
