Storage System Setup Wizard Errors

You may see the following error messages in the Storage System Setup Wizard.

Common error strings that appear in multiple places

•

"The specified system is currently in the storage system initialization process. Only one

initialization process can run at one time.”

This message displays when the wizards of two users try to initialize the same storage system

on the same SP. Only one wizard can initialize a storage system.

Two options are available when this error displays in a dialog box; you can click

Retry

or

Cancel

. When the error does not display in a dialog box, but rather inline, look for another

SP by serial number or wait a while and try again later.

•

"Unable to start SysManager. Make sure the storage system is running and in manual startup

mode."

Turn the storage system on and make sure it is running in manual startup mode.

This message displays either in a dialog box or inline. If the message displays in a dialog

box, you can click

Retry

or

Cancel

in the wizard. If the message appears inline, you can only

click

Next

in the wizard.

•

"Could not communicate with the server. Make sure you are currently connected to the

network."

This message displays when the client computer that is running the wizard cannot communicate

with the SP, such as when network connectivity is lost.
