The following are execution examples:
Lun Reset
Online(E) IO Block
NPIV Option

4 Execute the following command to delete the path that goes through the
.
Fibre Channel switch to be replaced:
Specify the device name (fscsi device) of the HBA connected to the Fibre
Channel switch that is to be replaced to delete the path (where n is the
instance number of the fscsi device).
# rmpath -p fscsin -d
Because the fscsi number found in step 1 is 1 (fscsi1), the result is as
follows:
# rmpath -p fscsi1 -d
5 Execute the following command to get the name of the parent device:
.
# lsdev -C -l fscsin -F parent
6 Delete the HBA device associated with the Fibre Channel switch that is to
.
be replaced.
# rmdev -dl fscsin -R
7 Replace the Fibre Channel switch.
.
8 Execute the following command to reconfigure the HBA device:
.
# cfgmgr -l fcsn
4-30
If the NPIV option is set to off:
Specify the HBA adapter number and bus number, and then execute
the command shown below. The following example shows how to
place the path in Offline (C) status when the path goes through an
HBA whose HBA adapter number is 08 and whose bus number is 11:
# /usr/DynamicLinkManager/bin/dlnkmgr offline -hba 08.11
If the NPIV option is set to on:
Use the fscsi number found in step 1 to execute the command
below. The following example shows how to place the path in Offline
(C) status when the path goes through fscsi number 1 (fscsi1):
# /usr/DynamicLinkManager/bin/dlnkmgr offline -hba 00.01
