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
