Change in DiskGroup agent
An optional attribute, ScanDisks, is introduced in the DiskGroup agent with the default value 0. This attribute is typically used in a hardware replication environment. It specifies whether to selectively scan the devices for all the disk paths that are associated with a VxVM disk group. Accordingly, the VxVM and the DMP attributes of a disk are refreshed before attempting to import a hardware clone or a hardware replicated device.
- If this attribute set to 1, a selective device scan is performed before the disk group import operation.
- If this attribute set to 0, a selective device scan is not performed. However, even when ScanDisks is set to 0, the disk group may fail during the first disk group import attempt. When such a failure occurs, if the corresponding error message contains the string “HARDWARE_MIRROR”, the DiskGroup agent performs a selective device scan. Thus, the chances of the disk group being imported successfully are increased.
