AIX: cfgmgr returning cfgpkcs11 -l pkcs11 0514-040 Error initializing a device into the kernel after clonning AIX from mksysb over a NIM

When cloning AIX 6.1 TL7 SP4 from mksysb receiving error message during first boot and boot process takes too long:

         0 Method error (/usr/lib/methods/cfgpkcs11 -l pkcs11 ):               
         0      0514-040 Error initializing a device into the kernel.

When running cfgmgr receiving this error:

Method error (/usr/lib/methods/cfgpkcs11 -l pkcs11 ):
          0514-040 Error initializing a device into the kernel.

cfgmgr -v

Listing defined devices shows pkcs11 device:

asrv01lpar12:/ # lsdev -Cc adapter | grep Defined
pkcs11 Defined         PKCS#11 Device

These steps helps to resolve problem with cfgmgr:

    Method error (/usr/lib/methods/cfgpkcs11 -l pkcs11 ):
           0514-040 Error initializing a device into the kernel.
    rmdev -l pkcs11
      pkcs11 Defined
    mv /var/security/pkcs11/meta /tmp/pkcs11_meta
    ll /var/security/pkcs11/tokens
    total 0
    dr-x------    2 root     system          256 Jan 28 2012  .
    dr-x------    3 root     system          256 Aug 14 19:55 ..
    mkdev -l pkcs11
    pkcs11 Available


Seem to be bug in AIX because the file /var/security/pkcs11/meta file is host-specific after pkcs11 is initialized and it should not be restored during mksysb restore with option recover device set to no.
The meta file from one host will be totally invalid on other hosts.
The meta file shouldn't be existed in a NEW complete system installation.
It is created when pkcs11 device driver is loaded and configured very first time on that host.


So in order to ensure NIM mksysb image works on installing hosts, we need exclude /var/security/pkcs11/meta and /var/security/pkcs11/tokens when creating mksysb image for NIM installation.
But /var/security/pkcs11/meta and /var/security/pkcs11/tokens should be included in mksysb when it is used for backup purpose only.
