When all computes nodes patch successfully,you’re ready to patch cell storage servers.
For compute nodes we use dbnodeupdate script/tool/utility.For cell storage you use patchmgr.
Go to folder downloaded patch,unzip the cell patch software.
Go into extracted folder create/copy cell_group file which has cell storage addresses and run command with prerequisite option.
[root@**** patch_188.8.131.52.0.190111]# ./patchmgr -cells cell_group -patch_check_prereq -rolling
If everything is good to go,you ‘re ready to run patch command.
