Solution Type Problem Resolution Sure Solution 1011275.1 : ERROR - gpio driver not installed / rscadm: Unable to reset RSC hardware
PreviouslyPublishedAs 215478 Symptoms On a system having an RSC (Remote System Control) card and the appropriate RSC packages installed, rscadm and/or rsc-config fail to reset the RSC. The error message is: # ./rscadm resetrsc Are you sure you want to reboot RSC (y/n)? y ERROR - gpio driver not installed rscadm: Unable to reset RSC hardware Resolution This can happen when the link /dev/gpio0 does not point to the correct device path. Most often this is caused by installing a system from the flash image of a different model also having an RSC, but with a different device path. In such a case we see a /dev/gpio1 which points to the correct device path. Example: # ls -l /dev/gpio* lrwxrwxrwx 1 root root 49 Jul 8 08:25 /dev/gpio0 -> ../devices/pci@8,700000/ebus@5/gpio@1,300600:gpio lrwxrwxrwx 1 root root 49 Jul 8 08:25 /dev/gpio1 -> ../devices/pci@9,700000/ebus@1/gpio@1,300600:gpio In the above example, a V890 was installed from a flash image of a V880. To resolve this, simply remove the existing gpio links and allow gpio0 to be created correctly by running devfsadm. # rm /dev/gpio* # devfsadm -v devfsadm[2467]: verbose: symlink /dev/gpio0 -> ../devices/pci@9,700000/ebus@1/gpio@1,300600:gpio # ls -l /dev/gpio* lrwxrwxrwx 1 root other 49 Jul 12 13:56 /dev/gpio0 -> ../devices/pci@9,700000/ebus@1/gpio@1,300600:gpio rscadm and rsc-config can now successfully reset the RSC card. Additional Information Bug ID: 4726924 illustrates the issue and was closed as "not a bug" since the problem was an incorrect link resulting from a flash install with an image from a different model.
