Dell PowerVault DL2000 - Manual (Page 22)

Depending on the error condition, automatic disk configuration may or may not be able to proceed. The
following table lists the error conditions that can occur during automatic disk configuration and recommends
you can proceed with automatic disk configuration.
Table 2. Automatic Disk Configuration Error Conditions
Error Condition Description Solution/Workaround
Unconfigured physical disks are
not all the same size
One or more physical disks vary in
capacity.
You can proceed with automatic disk
configuration, but, the RAID group is
formed as if all physical disks are the size
of the smallest physical disk. Additional
space on the larger disk(s) is not usable.
To avoid losing storage capacity, all
physical disks must be of the same
size.
Slot 0 is empty (applies to DL2200,
DL2100, DL2000)
If the selected standard configuration is
RAID 5 and a disk is available in slot 0,
automatic disk configuration assigns it as
a global hot spare.
You can proceed with automatic disk
configuration, but, a global hot spare is
not created.
You can add a physical disk in slot 0 at
a later time and automatic disk
configuration assigns that disk as a
global hot spare.
Slot 0 disk size is smaller than
other disks (applies to DL2200,
DL2100, DL2000)
A physical disk in slot 0 to be configured
as a global hot spare is smaller than one
or more physical disks in the remaining
slots in the storage enclosure.
You can proceed with automatic disk
configuration, but, this global hot spare
does not provide failover support for
larger physical disks.
Replace this physical disk with a disk
whose capacity is at least as large as
the remaining physical disks in the
storage enclosure.
The new disk is a SAS disk Automatic disk configuration is disabled
when any SAS disk drive is detected.
You cannot proceed with automatic disk
configuration.
Either remove the SAS drive or
replace the SAS drive with a SATA
drive.
The new disk is a SATA disk Automatic disk configuration is disabled
when any SATA disk drive is detected.
You cannot proceed with automatic disk
configuration.
Either remove the SATA drive or
replace the SATA drive with a SAS or
nearline SAS drive.
