Appendix B--- Disk Hot Swap Operation
Note: please implement 3016X internet intelligent storage device when RAID is in working
status.
Hot swap only be operated when RAID is in working status, otherwise it may result in data
loss in RAID device!
z
Ready status:
It only applies to RAID1/RAID5, e.g these disk groups are in RAID
synchronization. When disk group are in ready status, in the web configuration interface,
from disk management to RAID configuration, you can see the corresponding RAID group
status is
“
clean
，
degraded
，
recovering
”
.
z
Working status:
it only applies to RAID1/RAID5. It is a RAID status after synchronization.
When disk group are in ready status, in the web configuration interface, from disk
management to RAID configuration, you can see the corresponding RAID group status is
“
clean
，
degraded
，
recovering
”
.
z
Degraded status:
It only applies to RAID1/RAID5. e.g the working RAID disk group status
after hot swap a disk. When RAID is in degraded status, in the web configuration interface,
from disk management to RAID configuration, you can see the corresponding RAID group
status is
“
clean
，
degraded
”
.
Operation example
The RAID5 and RAID1 have the same hot swap operation steps. Now we take RAID5 as an
example.
In 3016X internet intelligent storage device, there is a RAID5 disk group consists of four disks
(dsk1, disk2, disk3, disk4.). All these four disks are in working status.
Note: 3016X internet intelligent storage device support max 16 SATA disks. But for
performance and safety consideration, we recommend RAID 5 consists of four to six
disks, RAID1 consists of two to three disks.
Note: Here we just take four disks as an example. When your disk amount is more than 4,
the operation is just the same.
1). Disk hot swap example.
In web configuration interface, from disk management to disk information, you can see the
information before hot swap. See Figure 8-1.
Here you can see the following information:
z
In 3016X internet intelligent storage device, disk group has four disks.
z
The four disks are: dsk1, disk2, disk3, disk4.
z
These four disks are corresponding to channel 1 to channel 4 respectively.
z
All disks are in running status, which means there is no error.
