NOTE

When building stripesets with drives of capacity 4 GB or greater, the

largest stripeset that can be built contains 11 members.

6.11 CLONE Utility Constraints

The CLONE utility cannot be used with partitioned units. When running the

CLONE utility in a dual-redundant controller configuration, do not issue any

CLI commands to devices that are involved in the clone operation.

7.0 Avoiding Problem Situations

In certain situations, you may experience unusual controller behavior.

Paragraphs 7.1 through 7.9 present information to help you avoid such

situations and to recover from them if they occur:

• HSUTIL Program Failure During a Code Load Firmware Upgrade

• Compaq Tru64 UNIX Patch Kits for Issue Resolution

• Unit Problems after Battery Low

• CLEAR_ERRORS LOST_DATA Command

• Only One Switch per CLI Command Recommended

• Hot Swapping Devices

• Write-Back Cache Battery Replacement

• Restoring Power after Emergency Cab Shutdown

• Using the CLI and CF Menu Simultaneously in a Dual Configuration

• Changing Preferred Access Device

7.1 HSUTIL Program Failure During a Code Load Firmware

Upgrade

As noted in Section 3.3, in a rare occurrence the HSZ40 controller may not be

able to use the HSUTIL program to perform a “code load” firmware upgrade to

TZ87/88/89 tape drives or any associated Automated Tape Library. In such a

case the HSUTIL program refuses to perform the upgrade because it

incorrectly determines that there is a tape present in the target tape drive when

there is none.
