4. HDLM Operation
206
Lun Reset : off
Online(E) IO Block : on
NPIV Option : off
Check the NPIV Option line.
3. Place in Offline (C) status the path that goes through the HBA 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 command shown below to delete the path connected to the HBA that
is to be replaced.
Specify the device name (
fscsi device) of the HBA that is to be replaced (where
n is the instance number of the fscsi device).
# rmpath -p fscsi
n -d
Because the fscsi number found in step 1 is 1 (fscsi1), the result is as follows:
# rmpath -p fscsi1 -d
5. If LUN security has been set up for the storage system, add the WWN of the new
