This section describes the Fsystem resource attribute (Flag).
If "Yes" is set, hvdet_gmount tries to recover the failure by re-mounting when it detects a failure. If this attempt fails, the Fault processing is executed.
The default value is "Yes."
Note
"No" is recommended to set to AUTORECOVER.
If you set "Yes," it is effective for the measures when an operator unmounts a file system mistakenly. However, it takes time for a switchover when Fsystem timeouts due to an I/O error, and so on because it tries to perform I/O again.
If an error is detected, hvdet_gmount repeats a recovery processing only for the number of times specified with the HV_GMOUNTMAXLOOP attribute as follows. Even though it cannot be recovered, perform a recovering processing specified times with the HV_GMOUNTMAXRETRY attribute.
The defaults values for HV_GMOUNTMAXLOOP and HVGMOUNTMAXRETRY are four and seven times respectively. The recovery processing for HV_GMOUNTMAXLOOP is executed in 0.5-second intervals while the recovery processing for HV_GMOUNTMAXRETRY is executed in 10-second intervals. Therefore, when a disk or path error cannot be recovered occurs, the re-try processing is executed in about 84 seconds, and then it is switched over.
Note
HV_GMOUNTMAXLOOP and HV_GMOUNTMAXRETRY are RMS environment variables. To change those values, set "export HV_GMOUNTMAXLOOP=value" and "export HV_GMOUNTMAXRETRY=value" to hvenv.local
