Linux Native Multipath IO timeout
My Oracle RAC 12.1.0.1 runs on ASM. ASM has an I/O timeout of 15 seconds. How do I find my Linux native multipath I/O timeout? I am running RedHat Linux 6 Enterprise, x86-64.
This is the device section of my multipath.conf
devices{
device {
vendor "NETAPP"
product "LUN.*"
path_grouping_policy group_by_prio
getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
path_selector "round-robin 0"
path_checker tur
features "3 queue_if_no_path pg_init_retries 50"
hardware_handler "0"
prio ontap
failback immediate
rr_weight uniform
rr_min_io 128
rr_min_io_rq 1
flush_on_last_del yes
fast_io_fail_tmo 5
dev_loss_tmo infinity
retain_attached_hw_handler yes
detect_prio yes
}
}
Thanks,
keith
