Preparation for replacing HBAs
Before you replace HBAs, perform the following procedure to ensure that the
acpiphp module has been loaded.
To ensure that the acpiphp module has been loaded:
1. Execute the lsmod OS command.
# /sbin/lsmod | grep acpiphp
acpiphp 58713 0
If the acpiphp module has been loaded, replace the HBAs as described in
Procedure for replacing HBAs on page 4-48. If the acpiphp module has
not been loaded, continue to step 2.
2. Create the acpiphp.modules file.
First, execute the following command:
# vi /etc/sysconfig/modules/acpiphp.modules
Next, edit the acpiphp.modules file as follows:
#/bin/bash
/sbin/modprobe acpiphp
Save the changes to the file, and then use the chmod OS command to set
execution permissions as follows:
# chmod 755 /etc/sysconfig/modules/acpiphp.modules
Finally, after the chmod command has been executed, confirm that the
execution permissions have been set as indicated by the underlined
portion below.
# ls -l /etc/sysconfig/modules/acpiphp.modules
-
rwxr-xr-x 1 root root 35 mm dd hh:mm /etc/sysconfig/modules/
acpiphp.modules
3. Load the acpiphp module.
Execute the acpiphp.modules file you created in step 2.
# /etc/sysconfig/modules/acpiphp.modules
After the above command has been executed, confirm that the acpiphp
module has been loaded.
# /sbin/lsmod | grep acpiphp
acpiphp 58713 0
