Modem connectivity
Adding a modem to one of your systems creates a potential entry point for unauthorized
access to your network. RSM for Storage modifies many characteristics and behaviors of the
system it is installed on to protect this entry point and to maximize the amount of control you
have in managing remote access.
In RSM, the modem used for remote access by IBM Service will not answer unless one of the
storage subsystems has an active alert or Remote Access has manually been enabled.
Normally, Remote Access is enabled automatically when an alert is sent to IBM, but you can
choose to wait for IBM Service to contact you when an alert is received and manually enable
Remote Access at that time.
On the RSM for Storage Remote Access window, click Enable Remote Access. This will
enable the modem to answer when called. Verify modem connectivity by calling the modem
phone number from a voice phone:
1. Most modems will either flash an LED or you might hear a sound when a call is being
received. If there is no indication that a call is being received:
a. Plug the phone cable into an analog voice phone and verify that a dial tone is present.
b. If a dial tone is present, hang up and then call this phone number from another phone
and verify that the phone you just connected rings.
c. Reconnect the phone cord to the modem connector labeled line #1.
2. Try again to verify the modem connectivity by calling the modem phone number from a
voice phone.
3. Check the instructions that came with the modem and review any troubleshooting
information.
To configure the Remote Access policy, click Remote Access from the Main Menu, as shown
in Figure 16-31 on page 524.
