Known Issues and Frequently
Asked Questions
This section describes known issues with the Deployment Toolkit (DTK)
utilities and scripts, including answers to some frequently asked questions.
Known Issues
The following issues are organized by DTK utility or other function.
General Issues
• Virtual disk creation and/or deletion takes a long time on
Microsoft Windows PE.
RAIDCFG Issues
• If you delete a virtual disk on PowerEdge Expandable RAID controller
(PERC) 4/IM on Windows PE, you need to reboot the system.
• Due to a rounding limitation, for RAID 0, RAID 1, and RAID 5,
RAIDCFG can accept a virtual disk size that is 1 MB greater than the
maximum allowable virtual disk size when creating a virtual disk. However,
RAIDCFG will create the maximum virtual disk size and not give an error.
If you need the maximum allowable virtual disk size, it is recommended
that you do not provide the size in the CLI and let RAIDCFG calculate
the size for the RAID type.
• Before creating a virtual disk using RAIDCFG on Cost-Effective RAID
Controller (CERC) Serial Advanced Technology Attachment (SATA)
1.5/2S and CERC SATA 1.5/6CH, initialize the array disk(s) through the
controller BIOS.
SYSCFG Issues
• Setup passwords and system passwords cannot be cleared using DTK.
• The Demand-based Power Management (DBPM) option does not work on
PowerEdge 1855 systems with BIOS versions earlier than A05.
