Installing A Controller - HP StorageWorks HSG80 Array Controller V8.7 Maintenance And Service Manual

CAUTION: Wait for FRUTIL to quiesce the device ports—indicated by an "All device
ports quiesced" message. Failure to allow the ports to quiesce might result in data
loss. Quiescing might take several minutes.
IMPORTANT: A countdown timer allows a total of 2 minutes to remove the controller. After
2 minutes, "this controller" exits FRUTIL and resumes operations. If this happens, return to
step 4 and proceed.
9. Remove the "other controller:"
CAUTION: For fiber optic cables without extender clips, thin needle-nose pliers must
be used to remove the cable from the controller without potentially damaging the cable
(see Figure 3–4).
a. Disconnect all host bus cables from the controller.
b. Disengage both retaining levers and remove the controller from the enclosure.
c. Place the controller in an antistatic bag or on a grounded antistatic mat.
10. Is a replacement controller available now?
• No. Enter N(o) and disconnect the PC or terminal from the controller
maintenance port.
FRUTIL will exit.
NOTE: If reverting to a single-controller configuration, fill the vacant controller bay with
a blank bezel to prevent the enclosure from developing a potential over-temperature
condition.
• Yes. Enter Y(es). Go to step 6 on page 3–22 and proceed.

Installing a Controller

Use the following steps to install a controller in a dual-redundant controller
configuration.
CAUTION: ESD can easily damage the controller. Wear a snug-fitting, grounded ESD
wrist strap.
1. Connect a PC or terminal to the maintenance port of the operational controller.
The controller connected to the PC or terminal becomes "this controller"; the controller
being installed becomes the "other controller."
