Replacing a faulty drive in the RAID system
The faulty drive is indicated in the management software of the respective option. Replace
the faulty drive with a new drive of the same type and capacity to return to the safe RAID1 or
RAID5 status after a fault.
You can find detailed information on drive replacement in the following sections:
•
"Expanding and assigning parameters to the device", "Replacing a defective hard disk drive
in the RAID system (Page 77)"
Integrating a new hard disk
A hard disk is integrated automatically into the RAID system if it fulfills one of the following
requirements:
•
The hard disk is brand new.
•
The hard disk is of the same type (e.g. SATA or SAS) as the rest of the hard disks in the
array.
•
The hard disk capacity is greater than or equal to the smallest hard disk in the array.
•
The hard disk is set up as a specific spare drive (dedicated hot spare) as a spare drive for a
specific RAID array.
5.2.2.2
Hardware RAID system
Hardware RAID adapter card with dedicated CPU and cache memory:
•
For applications with stringent requirements regarding low system disturbances of the
RAID system.
•
The RAID controller with PCIe x8 interface occupies one PCIe x8 or x16 expansion slot of
the device.
Requirements for Adaptec Storage Manager software
The following requirements must be met before you use the software for the first time during
commissioning:
•
4 GB main memory
•
The operating system is restarted.
•
Compatible Web browser is also installed manually:
–
Microsoft Internet Explorer is not compatible.
–
Recommendation: Microsoft Edge Chromium. You can find more detailed information
on the Internet: Microsoft Edge (
•
The operating system is password-protected.
•
Login and password of the operating system and Storage Manager software are the same.
The data backup takes place on SATA SSDs or HDDs. As a result, the system is able to
continue operation in the event of a defective hard disk or port connection problems, thereby
achieving high availability.
An optionally available hot-spare drive can further increase the availability of the system.
