Prepare and review Oracledba before hardware engineers perform storage operations

Before the hardware engineers perform operations on the storage (new storage or other operations on the storage), Oracle DBAs should prepare:

1. vg information hpux: vgdisplay, pvdisplay, vgdisplay-v vg_data aix: lsvg-o, lsvg, lsvg datavg, lsvg-l datavg, lspv 2.ocr + vd information (if rac is used) 3. datafile information (v $ dbfile, v $ datafile, dba_data_files) 4. OS log

After the storage personnel are completed, Oracle dba executes the above command again and reviews the two commands before and after to check whether there are any changes. Only when Oracle dba passes the verification, storage engineers can leave.
