This section explains how to change devices of file systems controlled by the Fsystem resource.
Note
In the VMware environment where the I/O fencing function is used, make sure that userApplication is Offline on all the nodes before stopping RMS.
If an error such as a resource failure or an OS panic has occurred right before stopping RMS, take the following steps first and then change the device:
Remove the cause of a fault or an error.
Start userApplication once and then stop it.
Make sure that userApplication stopped in step 2 becomes Offline successfully.
Operation Procedure:
Stop RMS of all the nodes.
If RMS is running, see "7.2.1.2 Stopping RMS" and stop RMS.
Change the settings in the "/etc/fstab.pcl" file.
See "6.7.3.2 Setting Up Fsystem Resources" and change the device that is described in the first field of the "/etc/fstab.pcl" file.
When you do this, do not change "#RMS#" at the beginning.
Execute the following procedures described in "6.7.3.2 Setting Up Fsystem Resources."
Confirm that the file system can be mounted.
Carry out tuning of the file system.
Start RMS.
Start RMS as described in "7.2.1.1 Starting RMS."
