HP IO Accelerator for BladeSystem c-Class - Manual (Page 17)

Maintenance 17
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"
