5-4 Configuration Errors to Avoid Unilateral Connection In the example shown in Figure 5-2, both the internal and external cables from the active controller are connected to the same ProLiant Storage System/F or /U. Likewise, the internal and external cables from the standby controller are connected to the second ProLiant Storage System/F or /U. This is also an error that the Verify function of the Online Storage Controller Recovery Utility flags. In addition, if there are drives in both ProLiant Storage Systems, both of the SMART-2 controllers will be attached to active SCSI buses, and the Online Storage Controller Recovery Utility will not allow the controllers to be merged. In the unlikely event that no drives were installed in the second ProLiant Storage System/F or /U, however, the Online Storage Controller Recovery Utility does not detect this error unless the Verify function is used.

5-4
Configuration Errors to Avoid
Unilateral Connection
In the example shown in Figure 5-2, both the internal and external cables from
the active controller are connected to the same ProLiant Storage System/F
or /U. Likewise, the internal and external cables from the standby controller are
connected to the second ProLiant Storage System/F or /U. This is also an error
that the
Verify
function of the Online Storage Controller Recovery Utility flags.
In addition, if there are drives in both ProLiant Storage Systems, both of the
SMART-2 controllers will be attached to active SCSI buses, and the Online
Storage Controller Recovery Utility will not allow the controllers to be merged.
In the unlikely event that no drives were installed in the second ProLiant
Storage System/F or /U, however, the Online Storage Controller Recovery
Utility does not detect this error unless the
Verify
function is used.
