To replace a Fibre Channel switch:
1
.
Execute the following command to find the fscsi number that
corresponds to the path that goes through the Fibre Channel switch that
is to be replaced (the path that goes through the HBA to which the Fibre
Channel switch is connected):
# lsdev -C | grep fscsi
The following are execution examples:
fscsi0 available 1H-08-02 FC SCSI I/O controller protocol device
fscsi1 available 11-08-02 FC SCSI I/O controller protocol device
In the second line of the above examples, 11 in 11-08-02 indicates the
bus number and 08 indicates the HBA adapter number. If the Fibre
Channel switch is connected to this HBA, the corresponding fscsi
number is 1.
2
.
Execute the dlmodmset utility for setting the HDLM execution environment
ODM to check the NPIV option setting.
# /usr/DynamicLinkManager/bin/dlmodmset -o
The following are execution examples:
Lun Reset : off
Online(E) IO Block : on
NPIV Option : off
OS Error Log Output : off
Check the NPIV Option line.
3
.
Place in Offline (C) status the path that goes through the Fibre Channel
switch to be replaced.
Depending on the NPIV option setting for the dlmodmset utility checked in
step 2, execute one of the following commands:
¢
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
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).
