APAR status

  • Closed as program error.

Error description

  • When an immutable/appendonly file at primary/cache is made
non-imm/non-app first using mmchattr and then immediately the
file is removed - then AFM has an issue where the file remove
cannot replicate to secondary/home because the file is still
imm/app and not allowed to be removed.

Local fix

  • Wait for the mmchattr -i no -a no <file> to be replicated first
to the secondary/home and file at home/secondary also becomes
non-imm/non-app first and later remove the file.

Problem summary

  • When an immutable/appendonly file at primary/cache is made
