In Online processing for Fsystem, fsck may be executed.
If fsck is executed during Online processing, the processing may not be completed within time set with ScriptTimeout. As a result, the startup or switchover processing fails.
To use Fsystem, set the ScriptTimeout value that the processing time of fsck is considered.
Do not access mountpoint specified in Fsystem from other than a userApplication.
During Offline processing, if accessing the mountpoint specified in Fsystem with other process, the Offline processing may fail and a switchover may not be performed.
Do not change the mountpoint name for Fsystem with such as mv command when a userApplication is Online.
If the mountpoint name is changed when Online, hvdet_gmount detects an error and a userApplication is switched. To change the mountpoint name temporarily, stop RMS first.
If 31 or more mountpoints registered in a single Fsystem resource exist, you need to change the default timeout value (180 seconds).
For the Timeout value of the Fsystem resource, "the number of mountpoints registered in single Fsystem x 6 seconds" or more needs to be set.
For example, if 31 mountpoints are registered in a single Fsystem resource, set "31 x 6 seconds = 186 seconds" or more to the Timeout attribute of the Fsystem resource.
The timeout value set in each Fsystem resource is the time until all processing completes for the mountpoints registered in the Fsystem resource.
For example, if three mountpoints; /mnt1, /mnt2, and /mnt3 are registered in the Fsystem resource, and also 100 seconds is set to the timeout value, the processing times out unless the processing of all three mountpoints completes within 100 seconds.
For the disk partition used in the Fsystem resource, it is necessary to create beforehand.
If it has not been created, Online processing fails.
If a shared disk cannot be accessed, double fault may occur.
If a shared disk cannot be accessed, the Fsystem resource becomes Faulted. In this case, mountpoints cannot be unmounted in Offline processing (this processing is conducted after Faulted processing), and then double fault may occur.
