Array Details and Tray Reconfiguration
Caution - Before performing these reconfiguration procedures, ensure that you back up your data to tape or other media. See also To Restore Array Defaults Information.
The array details page that is shown after clicking the tray Name link from the Administration page (see To View Array Information) enables the admin user to view brief array status and also add expansion units to or remove expansion units from an array.
A wizard guides you (in the admin user or role) through the expansion unit addition or removal. Before attempting these procedures, consider the following:
- The Sun StorEdge 6020 and 6120 Arrays System Manual contains more details about physically adding and removing expansion units and other array configuration changes. Please read the array configuration chapter in this manual before attempting this procedure. Note that the Sun StorEdge 6300 system does not allow access by telnet. The wizards described in this help perform the underlying commands needed to add or remove expansion units.
- Perform all reconfigurations while the system is offline and prevented from accepting I/O operations from the host system (that is, I/O operations have been quiesced).
- System reconfigurations involve power cycling of storage arrays.
- Evacuate any data stored on the arrays before removing trays. If you are adding trays, you might want to back up your existing data on the arrays.
Note - Depending on the current state of the selected array, the Add Expansion or Remove Expansion buttons might be disabled. For example, you cannot remove trays in a 2x2 configuration.
