Removing Hosts; Changing A Host's Name; Changing Host Mappings - HP P2000 G3 Reference Manual

Removing hosts

To remove hosts
1. Verify that the hosts you want to remove are not accessing volumes.
2. In the Configuration View panel, either:
• Right-click the system or Hosts and then select Provisioning > Remove Hosts.
• Right-click a host and select Provisioning > Remove Host.
3. In the main panel, select the hosts to remove. To select or clear all hosts, toggle the checkbox in the
heading row.
4. Click Remove Host(s). A confirmation dialog appears.
5. Click Remove to continue; otherwise, click Cancel. If you clicked Remove, a processing dialog appears.
If the task succeeds, the hosts are removed from the table and from the Configuration View panel.
When processing is complete a success dialog appears.
6. Click OK.

Changing a host's name

To change a host's name
1. In the Configuration View panel, right-click a host and select Provisioning > Rename Host.
2. Enter a new name that helps you easily identify the host; for example, MailServer_P1. A host name is
case sensitive and cannot already exist in the system. A name cannot include a comma, double quote,
or backslash.
3. Click Modify Name.

Changing host mappings

For each volume that is mapped to the selected host, you can create, modify, and delete explicit mappings.
To change a volume's default mapping, see
CAUTION: Volume mapping changes take effect immediately. Make changes that limit access to volumes
when the volumes are not in use. Be sure to unmount a mapped volume from a host system before
changing the mapping's LUN.
NOTE: You cannot map the secondary volume of a replication set.
NOTE: When mapping a volume to a host using the Linux ext3 file system, specify read-write access;
otherwise, the file system will be unable to mount the volume and will report an error such as "unknown
partition table."
To view host mappings
In the Configuration View panel, right-click a host and select Provisioning > Manage Host Mappings. The
main panel shows the following information about volumes mapped to the host:
• Type. Explicit or Default. Settings for an explicit mapping override the default mapping.
• Name. Volume name.
• Serial Number. Volume serial number.
• Ports. Controller host ports through which the volume is mapped to the host.
• LUN. Volume identifier presented to the host.
• Access. Volume access type: read-write, read-only, no-access (masked), or not-mapped.
