modify wwn

Description Use this command to modify the WWN and WWN nickname of a host. You must enable LUN

security before using this command (see modify lun_security, page 76).

Syntax modify wwn <portname>, <HostGrpNickName>, <oldwwn/oldwwnNickName>

[-wwn <newWwn> | -nickname <newWwnNickName>]

Arguments <portname>

The port whose WWN or WWN nickname is to be modified. <portname> must be specified

as one port. Port names must be specified in truncated form (for example, 1A and not CL1-A)

because the hyphen (-) is used to specify a range.

The host group nickname whose WWN or WWN nickname is to be modified. Only one

<hostgrpnickname> can be specified.

The WWN or WWN nickname whose WWN or WWN nickname has to be modified. Only

one <oldwwn/oldwwnNickName> can be specified.

[-wwn <newWwn>]

Modifies the WWN value (the worldwide name value for the host). This must be a 16-digit

hexadecimal value and must be unique within the port. -wwn must be specified if -nickname is

not specified, and cannot be used with -nickname.

[-nickname <newWwnNickName>]

Modifies the WWN nickname. WwnNickname is the nickname used for a WWN. WWN

nicknames are unique for a port, and must not be the same as any host group nickname within

the port. -nickname must be specified if -wwn is not specified, and cannot be used with -wwn.

Example

modify wwn 1A,nick1,wwnnick1 -wwn JJKHKJHHJGH23423

modify wwn 1A,nick1,wwnnick1 -nickname wwnnick1
