witness will be lost due network changes

Question

Hi If we know that witness for SRDF/Metro will be not reachable because of network maintenance works then what is the recommended way of action before witness is lost from network 1. do on all SRDF/Metro pairs suspend and then establish with -use_bias2. disable witness on secondary and primary array with symcfg disable -witness -symforce3. stop storvwlsd on witness4. or just do nothing because when witness lost then Metro pairs will turn into bias mode automatically In normal situation when only witness disappears from network I would choose number 4 but since we are moving routing from current network core devices to new ones then who knows how it will look like maybe only one site sees witness then only other and then maybe both. I know that all situations are well handled since both arrays will be up and also SAN links between sites but maybe it is good idea to disable using witness. Thank you in advance Alo
