9. The filesystem is now expanded. Use the following command to verify:
df –F vxfs
We are developing a utility that will update the unit label without unmounting it. This
will allow for truly dynamic filesystem expansion. Check our web site for more
information on this utility.
8.0 AVOIDING PROBLEM SITUATIONS
Under certain conditions, you may experience unusual controller behavior. This
section presents information to help you avoid such situations and to recover
from them if they occur.
8.1 Adding, Moving, and Changing Devices
The controller maintains a configuration map of a device’s type and location.
This map is used to communicate with devices. If you add, move, or change a
device while the controller is powered off without first changing the controller
configuration, the controller is not able to communicate with the changed device
when it returns to service.
If a device is removed by mistake while the controller is off, delete all containers
associated with the removed device after power has been restored to the
controller.
If a device is replaced while the controller is off, remove the device before
restoring power to the controller. Correctly remove the current device and add
the new device after restoring power to the controller.
See the HSG80 Array Controller ACS Version 8.5 Maintenance and Service
Guide for correct device removal and addition procedures.
8.2 Moving Storagesets
Move only normal storagesets. Do not move storagesets that are reconstructing
or reduced, or data corruption will result.
