Renaming a Alias name and Zone name in MDS switch Switch

[hutamit]

Hello!

I currently have MDS9148 SAN Switch. Zoning is already completed and Host can able to see the LUN. Due to some requirement, Host name is changed and the same changes I have to make in SAN Switch (Device-Alias and Zone name). Is there any way to make the changes without any impact to the host?

Thank you in advance for help with this issue!

RENAME ALIAS FOR HOSTS (vsan id of 10):

switch(config)# fcalias rename old-AliasName new-AliasName vsan 10

Hi Jaton,

Thanks for reply. The link is related to fcalias rename however In the switch, "show fcalias" is not giving any output.

The command "show device-alias database", is showing the device alias name I have to rename.

So you are running on device-alias and not fcalias.

So you want to rename a device-alias:

switch(config-device-alias-db)#

device-alias rename Renames an existing device alias with a new name.

old-device-name new-device-name

I already tried this option "device-alias rename old-device-name new-device-name", however the new name is not reflecting in Zone name. For example, host name is host_HBA1 and the Zone name is host_HBA1_SAN3S. After changing the host name with above command from host_HBA1 to host2_HBA1, the same is not reflecting in Zone name (From host_HBA1_SAN3S to host2_HBA1_SAN3S). Do I have to remove the zone from zoneset and create a new zone with new name?

Any help will be highly appreciated.

You will have to rename zones with its own command.
