Hi,
RAC 2 nodes, RHEL 5.10 Linux, 2 databases - old 10gR2 and newer 11gR2.
When running latest Oracheck utility, it says:
ASM Check: Linux Disk I/O Scheduler should be configured to Deadline (All ASM Instances)
I set it up under RedHat guidances (https://access.redhat.com/solutions/54164)
When running Orachk again, it says about warning again, so how must I configure this properly ?
WARNING => Linux Disk I/O Scheduler should be configured to Deadline
