DANGER: You are about to disable connection restriction upon disk setting failure. This operation may allow other disks to connect to the storage array and use the malfunctioning disk when the ERC fails to be set or write cache fails to be disabled, resulting in data loss risks.
Suggestion: Before performing this operation, ensure that connection restriction upon disk setting failure needs to be disabled. Ensure that:
1. This command is used only for data recovery.
2. Data will not be written to the malfunctioning disk.
3. The "change disk diskin modeselect_switch=on" command is executed to enable connection restriction upon disk setting failure after data is recovered.
