Upgrading the Subsystem
8. In a dual-redundant controller configuration, repeat steps 4 through 7 for the
“other controller.”
9. Mount the storage units on the host.
Downloading New Software
Use the CLCP to download new software to the program card while it’s installed in
the controller. Use the following steps to upgrade the software with CLCP:
1. Obtain the new software image file from a customer service representative.
NOTE: The image file can also be loaded by using StorageWorks Command
Console (SWCC) (see the SWCC documentation).
2. Load the image onto a PC or workstation using its file- or network-transfer
capabilities.
3. From a host console, quiesce all port activity and dismount the storage units in
the subsystem.
NOTE: Do not remove the program card.
4. Remove the ESD cover. If your program card is equipped with a write-protection
switch, disable write-protection by sliding the switch to the left, as shown in
Figure 3–2.
5. Connect a PC or terminal to the controller’s maintenance port.
