Method used to isolate disks

Method used to isolate disks:
1. Locating procedure:
The method is used to isolate disks impacting system services or proper running of the system.
a. In most bilateral isolation cases, it is recommended that the pre-failure configuration be used.
b. In the case of error code isolation and intermittent disconnection isolation, unilateral isolation and access, instead of slow disk isolation, are used.
2. Solution
a. Bilateral isolation and access (simulating disk rejection and acceptance)
Note:
Disk rejection is mostly used for RAID recovery. In other cases, it is recommended that the pre-failure configuration be used for disk rejection.
Isolation: Log in to the storage's MML mode and enter dev setdiskout enclosure ID slot ID to specify the enclosure number and slot number.
Access: Log in to the storage's MML mode and enter dev setdiskin enclosure ID slot ID to specify the enclosure number and slot number.
b. Unilateral isolation and access
Note:
It is mostly used for the error code isolation and intermittent disconnection isolation modes.
Error code isolation and intermittent disconnection isolation mostly occur on unilateral isolation (that is, the disk has one link). In this case, you need to connect the disk to the system by using a link and continue to use the disk. If the disk has single link again later, replace the disk.
Log in to the isolated controller.
Unilateral isolation: Log in to the storage's MML mode and enter dev setdiskout enclosure ID slot ID 1.
Unilateral access: Log in to the storage's MML mode and enter dev setdiskin enclosure ID slot ID 1.
After unilateral isolation is performed, on the OSM page, the disk indicator becomes yellow. After unilateral access is performed, the disk indicator turns normal.
