To perform a rolling upgrade, complete the following steps. For clarity, the terms
Controller A, Controller B, HSGA>, and HSGB> are used to help you identify which
controller is used.
CAUTION: Attempt a rolling upgrade only when each controller in a dual-redundant
configuration is at least 50% idle. Otherwise, I/Os may be dropped during the upgrade.
1. Connect a PC or terminal to the maintenance port of Controller A, if not already
done.
NOTE: If you have several servers with multiple LUNs in your storage area network (SAN), HP
recommends that you verify that all units are online by using the SHOW UNITS FULL CLI
command. Afterwards, use the Secure Path Manager to move all LUNs to the controller to be
updated last. (LUNs may be removed by either controller.)
2. Verify the utilization percentage for each controller by entering the following RUN
command:
HSGA> RUN VTDPY
The idle percentage for the HSG80 array controller is the first item displayed on
the second line of the VTDPY display. If the HSG80 array controller is less than
50% idle and the screen display indicates activity, the processing load is reduced.
See your operating system documentation for more information on reducing the
processing load.
NOTE: The default VTDPY display refreshes every ten seconds.
To exit VTDPY, press <Ctrl> C, and then enter the following:
HSGA> exit
3. Repeat step 2 above on the OTHER_CONTROLLER.
4. Disable the Command Console LUN (CCL) prior to upgrading if the HSG80 array
controller is running in SCSI-2 mode and the CCL is enabled:
a. Type the following command to verify the current SCSI mode:
HSGA> SHOW THIS_CONTROLLER
The following text is only a portion of the resulting display. Arrows point to the
pertinent status indication.
