Rename zone object in Brocade Switch

Latest Brocade firmware doesn't support alirename command to rename alias. Now there is one command called "zoneobjectrename" for these purpose. This command notonly renames alias, but also can be used to rename any zone object.

Usage

zoneobjectrename "objectName", "newName"

You can use this command for all zone object types, including cfg, zone, and
alias.This command changes the defined configuration. For the change to be preserved across switch reboots, save the configuration to nonvolatile memory with the cfgSave command. For the change to become effective, enable the configuration with the cfgEnable command.
 
for eg:-
 

swpro01:admin>zoneobjectrename "SPRO10_3_2_SWPRO01_88","HPUXS03_2_1_SWPRO01_88"
swpro01:admin>cfgsave
swpro01:admin>cfgenable "cfg01"

We were not sure about the reason for this error. There were no case reported from any connected devices and the hardware paths were referring towards host HBAs.
finally we decided to check with storage/SAN side and we started to trace the   device id mentioned in the error log. We managed to find the WWN of the connected device corresponding to the ID using this method.

48   4    0   0d3000   id  2G  Online  F-Port  10:00:00:e0:02:23:39:54 49   4    1   0d3100   id   2G Online  F-Port  10:00:00:e0:02:23:39:6b 50   4    2   0d3200   id   2G Online  F-Port  10:00:00:e0:02:23:3e:75 51   4    3   0d3300   id   2G Online  F-Port  10:00:00:e0:02:23:40:55     

All the device IDs mentioned in that error log were representing tape library interface managers.For some maintenance work hardware team rebooted the library on that date. Still the reason for this error was not clear, as there were no tape drives allocated to this server from that library.

Finally, We managed to find out the actual cause for this error.The reason behind this error was single initiator multiple targets(meaning single interface controller is zoned to multiple host including the host which reported this error).

How to obtain serial number for CISCO SAN switch

Use the show license host-id command to obtain the serial number for your switch. The host ID is also referred to as the switch serial number.


Example:-

switch10# show license host-id                            License hostid:VDH=JAF1342557V                               

How to use Terminal Services /console switch in Vista SP1

Microsoft has changed the mstsc switch to launch the Terminal Services client to log on to the console of the machine/server.

The switch is changed to /admin from /console.

The new switch to connect to the server's active console session is:

%systemroot%\system32\mstsc.exe /admin

start-->Run-->type Mstsc  and press Enter

Specify the IP address of the server along with /admin switch

Now you will get the console access of the server.
