20150813 00:20:59 Master SubnetManager on sm lid 1 sm guid 0x10e035c2e0a0a0 : SUN DCS 36P QDR xyzsw-ibb01 192.168.xx.xx

[root@xyzsw-iba01 ~]#


[root@xyzsw-ibb01 ~]# getmaster

Local SM enabled and running, state MASTER

20150813 00:21:00 Master SubnetManager on sm lid 1 sm guid 0x10e035c2e0a0a0 : SUN DCS 36P QDR xyzsw-ibb01 192.168.xx.xx

[root@xyzsw-ibb01 ~]#

Here xyzsw-ibb01 is the Subnet Manager

Step2:Create ibswitches.lst

cd /u01/exa_img_upg/CELL/patch_PATCHNUMBER


# vi ibswitches.lst

xyzsw-ibb01

xyzsw-iba01

Step 3:Run the pre-requisite checks                                                       

#./patchmgr -ibswitches ibswitches.lst -upgrade -ibswitch_precheck

Note:  If the output from the comma nd shows overall status is SUCCESS, then proceed with the upgrade.

If the output from the command shows overall status is FAIL, then review the error summary in the output to determine which checks failed, and then correct the errors.  After the errors have been corrected, rerun the pre-requisite checks until it is successful.

Step 4: Upgrade the switches

#./patchmgr -ibswitches ibswitches.lst -upgrade

Step 5: Check the output from the command, and verify the upgrade

The output should show SUCCESS. If there are errors, then correct the errors and run the upgrade command again.
