Fibre to SAS/SATA Disk Array
112 User Manual
5.4.6 Set Disk To Be Failed
It sets a normal working disk as failed so that users can test some of the features and
functions.
NOTE: When you want to set a disk as failed, please contact your
vendor’s support engineer for assistance.
5.4.7 Activate Failed Disk
It forces the current failed disk in the system to be back online. Activate Failed Disk
function has no effect on the removed disks, because a removed disk does not give the
controller a chance to mark it as failure .
Followings are considered as
Removed-Disk :
(1). Manually removed by user
(2). Losing PHY connection due to bad connector, cable, backplane
(3). Losing PHY connection due to disk fail
Basically, in the eyes of the controller, the disk suddenly disappears due to whatever reason.
