Data that is not written by the host (for example, data written by XP Business Copy) is asynchronously
destaged to the external array regardless of the Cache Mode setting.
Check the following before changing the cache mode of the external volume.
•
Whether the LU is part of a LUSE. When it constitutes a part of a LUSE, the cache mode setting
should be same among all LUs which constitute the LUSE LU.
Whether the bind mode of a Cache LUN is set. When bind mode is set, you cannot change
the cache mode from Enable to Disable. To change the cache mode to Disable, first cancel
the setting for XP Cache LUN or change the cache residency mode to the priority mode.
•
Whether the IO Suppression mode is set to Disable. When the IO Suppression mode is set to
Enable, you cannot change the cache mode from Disable to Enable.
Whether the volume is not a remote command device. When the volume is a remote command
device, you cannot change the cache mode from Disable to Enable.
The procedures for changing the cache mode of the external volume are described as follows.
