NOTE
Before collecting data through the Support Save feature, you may want to disable auto-recovery on
the host system. This is because when adapters are reset after an auto-recovery from a failure,
traces initiated before the failure may be lost or overwritten.
To disable auto-recovery, use the following commands.
• For Linux, use the following commands.
- To disable auto-recovery for the network (BNA) driver.
insmod bna.ko bnad_ioc_auto_recover=0
- To disable auto-recovery for the storage (BFA) driver.
insmod bfa.ko bnad_ioc_auto_recover=0
• For VMware, use the following commands.
- To unload and load the network (BNA) driver with IOC auto-recovery disabled, use the
following commands.
esxcfg-module -u bna
esxcfg-module bna bnad_ioc_auto_recover=0
- To disable IOC auto-recovery for the BNA driver across reboots, use the following
command.
esxcfg-module -s "bnad_ioc_auto_recover=0" bna
- To unload and load the network (BFA) driver with IOC auto-recovery disabled, use the
following commands.
esxcfg-module -u bfa
esxcfg-module bfa bfad_ioc_auto_recover=0
- To disable IOC auto-recovery for the BFA driver across reboots, use the following command.
esxcfg-module -s "ioc_auto_recover=0" bfa
