Menu Advanced Setup: Configure Controller; Menu Advanced Setup: Configure Controller, Controller Settings - ICP RS Series User Manual

The „ERROR" state of an Array Drive is very critical. There are several procedures in the ICP
Controller's firmware to handle such cases and bring back the Array Drive into operation
without loosing data. The most suitable procedure for the specific case, should be elabo-
rated with your system administrator or our technical support. (Note: ICP vortex offers 2-
day RAID Workshops in our training center, which also focus on the resolution of such
problems.)

Within the Controller Settings all relevant
parameters and settings concerning the
ICP Controller itself can be changed. All
information concerning Physical, Logical,
Array and Host Drives are stored twice
(primary and secondary configuration data) on
each hard disk. I.e., the ICP Controller
itself carries no configuration data of a
specific disk array. Out of this reason, the
migration of Host Drives between ICP
Controllers is very easy and secure, even
if the SCSI IDs and channels are changed.
Simply connect the hard disks to the new
ICP Controller, and the Host Drives will
automatically available again.
The various parameters and settings have
