Registering a Host Group and an LDEV Group in a Security Group
Now that you have classified your security group as an access group, your next (and the last) task is
to register your host group and LDEV group into the security group. When you finish registration, the
volumes in the LDEV group are secured and can only be accessed by hosts in the host group. Other
hosts cannot access the volumes.
To register a host group and an LDEV group into a security group:
1. Ensure that you are in Modify mode.
2. In the Volume Security window (Figure 4), double-click an LDKC number.
3. Right-click a security group.
A pop-up menu appears.
4. Select Specify and then Security Group from the pop-up menu.
The Specify Security Group dialog box (Figure 14) appears.
5. Use the Select Security Group drop-down list to select the security group in which you want to
register a host group and an LDEV group.
6. Use the Host Group drop-down list to select the host group that you want to register in the security
group.
7. Use the LDEV Group drop-down list to select the LDEV group that you want to register in the se-
curity group, and then click OK.
8. Click Apply in the Volume Security window (Figure 4).
A message appears and asks if you want to apply the settings to the storage system.
9. Click Yes.
The settings are applied to the storage system.
CAUTION:
If the Error Detail dialog box (section “The Error Detail Dialog Box” on page 41) appears, see
the
Caution
in “Port-Level Security Implementation” on page 10 and then remove errors.
Prohibiting Host Access
Volume Security enables you to prohibit all the hosts from accessing the specified volumes. To do this,
take the following major steps:
• Creating an LDEV group (see “Creating an LDEV Group” on page 53)
• Registering volumes in the LDEV group (see “Registering Volumes in an LDEV Group” on page 54)
• Creating a security group and classifying the security group as a pool group (see
“Creating a Security Group for Use As a Pool Group” on page 55)
• Registering the LDEV group in the security group
(“Registering an LDEV Group in a Security Group” on page 56)
Creating an LDEV Group
To specify volumes that should be secured, you must create an LDEV group and then register the
volumes in the LDEV group.
