Displays the rejected device-alias command
switch(config-device-alias-db)# device-alias name dev10 pwwn 10:10:10:10:10:10:10:10
switch(config-device-alias-db)# device-alias rename dev10 new-dev10
Command rejected. Device-alias reused in current session :dev10
Please use 'show device-alias session rejected' to display the rejected set of commands and
for the device-alias best-practices recommendation.
switch(config-device-alias-db)#
If a PWWN is reused while configuring an add or delete command, then the command fails and gets
moved to the rejected list.
Displays the rejected device-alias command
switch(config-device-alias-db)# device-alias name dev11 pwwn 11:11:11:11:11:11:11:11
switch(config-device-alias-db)# no device-alias name dev11
Command rejected. Pwwn reused in current session: 11:11:11:11:11:11:11:11 is mapped to
device-alias dev11
Please use 'show device-alias session rejected' to display the rejected set of commands and
for the device-alias best-practices recommendation.
switch(config-device-alias-db)#
If a device-alias name is reused in an add command which was earlier being renamed in a rename
command, the command fails and gets moved to the rejected list.
switch(config-device-alias-db)# device-alias rename da3 new-da3
switch(config-device-alias-db)# device-alias name da3 pwwn 2:2:2:2:3:3:3:3
Command rejected. Device-alias name reused in current session: da3
Please use 'show device-alias session rejected' to display the rejected set of commands and
for the device-alias best-practices recommendation.
switch(config-device-alias-db)#
Displays the rejected device-alias command
The rejected set of commands can be displayed using the show device-alias session rejected command.
switch(config-device-alias-db)# show device-alias session rejected
To avoid command rejections, within a device alias session
Do not reuse:
a) a device alias name while configuring a rename command
b) a PWWN while configuring an add or delete command
c) a device alias name already renamed while configuring add command
Rejected commands must be committed in a separate device alias session
which may cause traffic interruption for those devices. Plan accordingly.
