The following page explains how to manually configure AIX hosts to work with InfiniBox systems.
If you are using Host PowerTools, the configuration is done by running infinihost settings check.
It is recommended to use Host PowerTools on the available platforms and perform the manual instructions mentioned below on OS versions where Host PowerTools is not available.
Configuring the ODM
Download the INFINIDAT ODM file from here
Copy it to the AIX host.
Then, run:
rpm -Uvh <infinidat-odm-filepath.rpm>
Configure the HBA driver according to best practices
Find all FC HBA drivers:
lsparent -C -k fcp -F name
For each driver, find the value of the error recovery policy:
lsattr -El <driver> -a fc_err_recov -F value
If the error recovery policy is not "fast_fail", check that there are no FC LUNs mapped to the host and change the policy by running:
chdev -l <name> -a fc_err_recov=fast_fail
AIX space reclamation
Space reclamation is applicable for the following AIX versions:
- AIX 6.1 TL9 or later
- AIX 7.1 TL3 or later
- AIX 7.2
Enabling space reclamation on AIX
Check to see whether space reclamation is enabled:
odmget -q "attribute=lbp_enabled and uniquetype=disk/fcp/NFINIDAT" PdAt
If there is no output for this command, create the file /tmp/odmtp
:
PdAt: uniquetype = "disk/fcp/NFINIDAT" attribute = "lbp_enabled" deflt = "true" values = "true,false" width = "" type = "R" generic = "" rep = "sl" nls_index = 0
Run the following command:
odmadd /tmp/odmtp
Run the following command to verify that space reclamation is enabled:
odmget -q "attribute=lbp_enabled and uniquetype=disk/fcp/NFINIDAT" PdAt
You should see the following output :
PdAt: uniquetype = "disk/fcp/NFINIDAT" attribute = "lbp_enabled" deflt = "true" values = "true,false" width = "" type = "R" generic = "" rep = "sl" nls_index = 0
After getting the output displayed above run the bosboot
command:
bosboot -a
Reconfigure the disk devices by stopping the I/O activity for each InfiniBox disk and running the following commands for each one:
rmdev -l hdiskX mkdev -l hdiskX
