Dell PowerVault DR2000v - Manual (Page 34)

ID Issue Description Workaround/Solution
failure condition from
occurring, observe
the following best
practice:
Ensure that before an
external expansion
shelf enclosure is
cabled to and
powered on to a
Release 2.0 DR4000
or DR4100 system
only after the DR
Series system has
been powered down.
• Power on the DR4000 or DR4100 system.
13580 User intervention is
required when booting
up a system that was
rebooted due to a shelf
going offline. This condition can
occur when an
external expansion
shelf enclosure goes
offline, which
requires that the DR
Series system be
rebooted. During the
DR Series system
boot up, it halts in the
PowerEdge RAID
Controller (PERC)
H800 configuration
process, and prompts
you to press to
import the Foreign
Disks. To resolve this issue, press to import the
Foreign Disks, and allow the boot up process
for the DR Series system to complete and
boot normally. Once the process completes
normally, the DR Series system will come up,
and enter its Operational mode.
13790 DR Series system
performance drops
when background
initialization runs on an
external expansion
shelf. Whenever an
external expansion
shelf enclosure is
added to the DR
Series system, this
causes a one-time
only impact to the DR
Series system
performance.
The impact is a result
of the background
initialization (BGI)
process running for
an external
expansion shelf (the
system RAID disks
require such
initialization).
There is no workaround for BGI. This is a one-
time only process that occurs when an
external expansion shelf enclosure is added.
During BGI that is associated with the
addition of an external expansion shelf
enclosure, you should expect that
performance for the DR Series system will be
slower than usual.
