Hello: I have been observing an anomaly during LPAR migrations between a couple of P8 systems.
This is the problem. After migrating an LPAR, the PPC mobility code receives RTAS requests to delete nodes with platform-/hardware-specific attributes when restarting the kernel after a migration. My example is for migration between a P8 Alpine and a P8 Brazos. Among the nodes that I see being deleted are 'ibm,random-v1', 'ibm,compression-v1', 'ibm,platform-facilities', and 'ibm,sym-encryption-v1'. Of these nodes, the following are created during initial boot by calls to vio_register_driver: drivers/char/hw_random/pseries-rng.c ibm,random-v1 drivers/crypto/nx/nx-842-pseries.c ibm,compression-v1 drivers/crypto/nx/nx.c ibm,sym-encryption-v1 After the migration, these nodes are deleted, but nothing recreates them. If I boot the LPAR on the target system, the nodes are added again. My question is how do we recreate these nodes after migration? Thanks. -- Michael W.
