Although data written to the IO Accelerator device is not lost due to unmanaged shutdowns, important data structures might not have been properly committed to the device. This consistency check repairs these data structures.

Disabling the IO Accelerator VSL

The driver automatically loads by default when the operating system starts. You can disable IO Accelerator auto-load for diagnostic or troubleshooting purposes.

To disable IO Accelerator driver auto-load:

1.Use the following command:

$ pfexec rem_drv iomemo

The ioDrive ioMemory VSL does not load, so the device is not available to users.

2.Proceed with troubleshooting to correct the problem.

Enabling the IO Accelerator VSL

To re-enable the IO Accelerator VSL after maintenance, run the following command:

$ pfexec /usr/sbin/add_drv -i "pci1aed,1005" "pciex1aed,1005" "pci1aed,1003"

"pciex1aed,1003" "pci1aed,1010" "pciex1aed,1010" "pci1014,3c3" "pci103c,324d" "pci103c,324e" "pci103c,178b" "pci103c,178c" "pci103c,178d" "pci103c,178e" "pci103c,176f" "pci103c,1770" -m "*0666 root sys" iomemory-vsl
