7.0 Preparing the HSZ70

Use the following steps to prepare the HSZ70 for upgrade:

1. Connect a PC or terminal to the operational controller’s maintenance port. The controller that

you are connected to is “this controller.”

2. If the HSZ70 storagesets were originally created with the SAVE_CONFIGURATION option

enabled then the current configuration of the HSZ70 will be retained on the disk in that

storageset. To determine if storageset was initialized with SAVE_CONFIGURATION

enabled use the command:

HSZ70> SHOW DEVICES FULL

In the output that is displayed search for the phrase:

“Configuration being backed up on this container”

If that statement is displayed, then the HSZ70 configuration is being saved on the device and

portions of the configuration can be restored to the HSG80 once it is installed. If the

statement is not displayed, the configuration has not been saved to the device and can only be

restored using SWCC or by manually recreating the storagesets from the information that will

be recorded in Step 2 below. Tru64 users will recreate storagesets manually using the CLI

interface.

1) If the configuration is being saved on a device then force an update of the configuration

using the following commands:

HSZ70> SET unit name WRITE_PROTECT

HSZ70> SET unit name NOWRITE_PROTECT

Where unit name is the name of a unit with save configuration enabled on the HSZ70, e.g.

D100

NOTE

If any of your storagesets are JBOD units, it is IMPERATIVE

to record their configuration as detailed in Section 4.0 of this

document. Because the configuration restore operation on the

HSG80 cannot restore units; failure to record this information

manually will cause it to be lost.

2) Obtain the disk and unit information with the following commands:

HSZ70> SHOW UNITS FULL

HSZ70> SHOW STORAGESETS FULL

Record this information in the Unit Table and the Storageset Table provided in

Appendix A of this document.
