IBM AIX on POWER Systems (64-bit)
You are using Oracle RAC 11gR2 on AIX 7.1 and have a diskgroup ACFS, ACFS volume enabled and an ACFS mounted filesystem for rman external tables files (large files).
The ACFS volume works correctly but is having a poor write speed.
Also, Legato is being used as the backup tool.
Ensure that Virtual memory (VMM) is tuned per the IBM recommendations.
