NOTE
If all the units configured on the dual controller pair are
“ONLINE” to only one of the controllers (i.e. the other
controller is in stand by mode), then all the devices will show
only one Product ID. The controller which has the units
“ONLINE” is the master controller. Go to Step 2 and perform
Steps 2 through 13. It is not necessary in this case to perform
Step 14.
b. Use the command below to determine which device the root file system is
mounted on.
# df
Filesystem 512-blocks Used Avail Capacity Mounted on
/dev/disk/dsk4a 338542 276436 28250 91% /
/dev/disk/dsk4g 3389096 520056 2530130 18% /usr
/proc 0 0 0 100% /proc
In the example above the root file system is mounted on dsk4.
c.
Shut the system down to single-user mode. This will prevent background
processes from touching the disks while this procedure is in progress.
# shutdown now
d. If the root file system is not mounted on a unit configured on the controller
pair, choose either of the controllers to be the "master" controller in the
upgrade operation below. Go to step 2.
If the root file system is mounted on a unit configured on the controller
pair, then do the following in order to determine which is the master
controller.
e.
Connect the CLI interface to one of the controllers and perform the
SHOW <UNIT> command for the unit with the root device (D600 in case
of the example).
