Capturing Boot Debug

Question

Capturing Boot Debug

Answer

This document can be used to assist in capturing boot debug information which may help determine why a system is hanging during IPL.These steps are valid for AIX 5L and AIX 6.1.

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.

Breaking limits of LVM, Physical Partitions, Volume Groups in AIX

Are you facing the situation that you can not extend LUN or mirror smaller LUNs to one big LUN in AIX because you reached limit of Physical Partitions in Volume Group?

extendvg VGname hdisk4
      0516-1254 extendvg: Changing the PVID in the ODM.
      0516-1162 extendvg: Warning, The Physical Partition Size of 512 requires the
              creation of 1140 partitions for hdisk4.  The limitation for volume group
              VGname is 1016 physical partitions per physical volume.  Use chvg command
              with -t option to attempt to change the maximum Physical Partitions per
              Physical volume for this volume group.
