create wwn

Description Use this command to add WWNs to host groups. Each host group can have up to 255 WWNs and

each port can have a maximum of 128 (XP128/XP1024) or 256 (XP10000/XP12000) host groups.

After the WWN is added to the host group, it has access to the LUNs in the host group.

Syntax create wwn <portname...>, <hostgrpnickname>,

<Wwn~WwnNickname...>

Arguments <portname...>

The port to which the WWNs are to be added. <portname> can be specified as one port, a set

of ports, or a range of ports (for example, 1A or 1A:1C:1D or 1A-1E). Port names must be

specified in truncated form (for example, 1A and not CL1-A) because the hyphen (-) is used to

specify a range. If more than one port is specified, then the WWNs are added to the host group

nickname in all the ports.

The host group to which the WWNs are to be added. Only one <hostgrpnickname> can be

specified.

<Wwn~WwnNickname...>

<Wwn> specifies the worldwide name for the host. This must be a 16-digit hexadecimal value,

must be unique within the port, and is mandatory.

<WwnNickname> is the nickname used for a WWN. WWN nicknames must be unique for a

port, and must not be the same as any host group nickname within the port. The nickname is

optional.

WWN and its nickname must be separated by a tilde (~). More than one set of

<Wwn~WwnNickname> pairs can be specified. The WWNs are added to the

<hostgrpnickname> in all the specified ports.
