Recovery Procedures
Disk Service Support
This section contains the procedures and information to recover from disk unit
failures with a minimum loss of customer data.
The procedures in this section do not give support to rack-mounted disk units
such as an IBM 9337. For disk service support on rack-mounted disk units, use the
FC 504x Problem Analysis and Repair and Parts, SY44–4934
information.
The procedures in this section do not give support to IBM 2105 disk units. Use the
″
IBM 2105 maintenance
″
information for disk service support.
Start all service actions at “Start Disk Service Here” on page 894 and follow the
steps in the procedures to determine the following:
v
The storage protection method that is used by the customer
v
When and how to save customer data
v
When to exchange a failing disk unit
v
