You set up InfoShield by either excluding or including hosts on a list for
each partition LUN. The list can include or exclude up to 64 specific
hosts or all hosts for each partition LUN.
For example, in Figure 56 , 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.
6.3.4.1 Viewing Known WWNs
You can view the global host list, which includes the last 64 host WWNs
that the EF2800 is aware of on your SAN. The EF2800 will be aware of
any host that was started since the EF2800 was last restarted. Typically,
hosts scan for devices during their start-up process. When this happens,
the EF2800 saves the WWN information for the host, but does not retain
the information after you restart the EF2800 unless you have given the
host a nickname. The list includes the last 64 hosts that started or that
you gave a nickname.
You can determine which WWN is for which host by starting one host
at a time or scanning for devices from a host, 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:
• From SAM, select
Manage EF2800
>
LUN Management
>
Manage
Global Host List
.
The Manage Global Host List page displays with a list of known
host WWNs and nicknames you have given them. The WWNs are
listed according to when they scanned for devices. The host that
scanned for devices most recently is listed first.
N
OTE
: A host’s WWN is placed at the top of the known hosts list
whenever the host performs a device discovery or bus scanning type of
operation.
