5.1 Using FRUTIL to Insert a New Controller
When using FRUTIL to insert a new controller in a dual-redundant controller
configuration, the user will see a new set of instructions after the new controller
has been inserted:
If the other controller did not restart, follow these steps:
1. Press and hold the other controller’s reset button.
2. Insert the other controller’s program card.
3. Release the reset button.
NOTE
Be aware that running FRUTIL will quiesce
all I/O. Consequently, never run this
program when under heavy load.
5.2 Dual External Cache Battery Failures
The HSG80 Array Controller cache policy provides for proper handling of a
single ECB failure as described in Table 2-8 of the HSG80 Array Controller
ACS Version 8.5 Configuration and CLI Reference Guide. For dual ECB
failures, Table 2-8 states that no failover occurs. For this release, if a dual ECB
failure is detected both controllers will be restarted.
5.3 Fault Management Utility (FMU)
For this release, the number of last failure entries maintained by FMU has been
reduced from 16 to 4.
6.0 SAVING YOUR CONFIGURATION
6.1 Saving a Configuration to Previously Initialized Storagesets
When enabled, the SAVE_CONFIGURATION switch allows you to do the
following on single-controller configurations only:
• Save a configuration to a disk or storageset. The configuration may be
retrieved later and downloaded onto a replacement controller.
• Retain code patches to the operating software.
