182 Upgrade and Maintenance Manual TX2550 M4
Hard disk drive (HDD) / solid state drive (SSD)
7.3.8.1 Preliminary steps
Ê If the HDD/SSD module to be removed is combined into a RAID array,
please proceed as follows:
In order to permanently remove an operational HDD module that is part of a
RAID array from the server, you first need to delete the array using
ServerView RAID Manager.
V CAUTION!
All data on all HDDs/SSDs in the array will be lost when deleting the
RAID array! Be sure to back up your data before deleting a RAID
array. For more information, see the "ServerView Suite RAID
Management" user guide.
Ê When working on a floorstand model, open the HDD bay cover, see section
"Removing the drive covers" on page 64.
RAID level Procedure
RAID 0
V CAUTION!
RAID 0 provides no data redundancy.
In case of an HDD module is defect, all data are
lost!
RAID 1
RAID 5
Removing an HDD module from a RAID 1 or RAID 5 array
will not result in data loss.
However, the removed drive needs to be replaced
immediately by an HDD module of the same or larger
capacity.
I After replacing the HDD module, RAID rebuild will
be performed as a background process, see
section "Performing a RAID array rebuild" on
page 128.
