(you need to manually switch the hard disk hung under A control to B control first.

The detailed steps are as follows: (collect storage subsystem-view---profile-All first, select all, collect and store the existing information in case of an error, analyze and use it during recovery; upgrade the hard disk microcode when the hard disk microcode is JFQ3,JFQ4 and then change it)

In SM, use the right mouse button to click 0 (raid5) > 1 (500G) > > change > > Cache Settings, remove the check mark from the box in front of Enable read caching, Enable write caching and Enable write caching without batteries, click OK, that is, turn off Cache; use the right mouse button to click Arr1 > > 1 (logical disk 1) > Change > > Ownership/Preferred Path > > Controller in Slot A, select Yes, and cut the hard disk on B to A

When the battery is in charge time, the green indicator of the power supply will continue to blink until the charging is complete (about 8-12 hours), the green light will turn on, and the battery status will change from charging to optimal. The battery in the charging state can be used normally.

6. Then in the right column, Back column, click controller A with the right mouse button, select Place > > online, that is, open controller A; use the right mouse button to click 0 (raid5) > > 1 (500G) (logical disk 1) > > Change > > Ownership/Preferred Path > > Controller in Slot B, select Yes, and switch the hard drive that was originally cut to B back to A.

7. Click 0 (raid5) > > 1 (500G) > > change > > Cache Settings with the right mouse button, add the check mark of the small box in front of Enable read caching, Enable write caching and Enable write caching without batteries, and click OK to open Cache.
