Managing Arrays & Partitions
145
Figure 3–5 shows an example of how you can use InfoShield.
Figure 3–5 InfoShield example
For example, in Figure 3–5 , Array A has two partitions. Partition 1 has an include list that contains only
Accounting, so only the Accounting server can access partition 1. Array B, partition 3 has an exclude list
that contains only the Web server, so all hosts
except the Web server can access the partition. Array C
uses the default setting, Include All Hosts, which permits all hosts to access the array.
C.3.8.1 Viewing Known WWNs
You can view a list of 16 host WWNs that the X24 Subsystem is aware of on your SAN. The X24
Subsystem will be aware of any host that was started since the X24 Subsystem was last restarted.
Typically, hosts scan for devices during their start process. When this happens, the X24 Subsystem
saves the WWN information for the host and retains the information even after you restart the X24
Subsystem. The list includes the last 16 hosts that started or that you named.
You can determine which WWN is for which host by starting one host at a time or scanning for devices
from a host, and then viewing the WWN list. The host that scanned for devices most recently is first on
the list. You can then give the hosts nicknames you recognize, for example you can use the computer
name that has already been assigned to each host, to make InfoShield easier to manage.
To view known WWNs:
