4. If you selected hard addressing, you will be asked to supply an address to
be used. It is expected that the number will be entered in hexadecimal. If
you enter a zero, then the Auto-Select feature will be enabled. Only
certain ALPA values are valid, if you choose an invalid address, then you
will be asked to try again.
5. You will now be asked whether the card should be re-started when this
new address setting is applied to the selected interface card. If you
respond with a Yes to multiple interface cards, then they will go through
their re-start sequence at the same time.
Caution Re-starting an interface card will stop any data flowing through
that card, so any backup in progress will fail.
Once you have changed the pending settings of all of the interface cards that
you wish to change, do the following:
6. Select
[4] to Apply those pending settings to all of the Fibre Channel
interface cards. Only the interface cards marked as Restart will have those
settings take effect immediately.
Placing a Fibre Channel Interface Card Off-Line Using Telnet
It is not necessary to remove power from the IM in order to remove a Fibre
Channel interface card, but it is highly desirable to inform the firmware of your
intention to do so. Placing the interface card Off-Line tells the firmware on the
RMC, the controller card, and the interface card that the card is going to be
removed. When it is ready for removal, the LED on the upper right side of the
card will turn yellow.
To place a Fibre Channel interface card off-line (for removal) using Telnet, do
the following:
1. Log into the IM via a Telnet session as described in
Accessing Telnet on
page 38.
2. Select [3] from the Main menu.
3. Select
[4] from the Interface Card menu informing the firmware that you
are removing an interface card.
4. Supply the slot number of the interface card that you wish to place
Off-Line. The slot number represents the interface card’s position in the IM
(see Figure 6 on page 46).
