Q: When I execute RAIDCFG with the RAID level of "01," RAIDCFG
creates RAID 1, not RAID 01.
A: This behavior occurs because the RAIDCFG CLI parser ignores zeros
preceding any parameter value. For example,
-r=01 will be parsed as -r=1.
Q: On PowerEdge 1655MC system running embedded Linux, RAIDCFG
displays the error: megadev: Bad file descriptor.
A: Ignore this message. The error message is generated by Megalib because it
is trying to open a device driver that is not present on your system.
Q: What is strict creation?
A: Strict creation is an optional flag that has been added to the create virtual
disk command. It allows you to create virtual disks only if the array disks (that
is, hard drives) are within a specified percentage of disk space of each other.
Q: Why is the drive location of array disks displayed like 0:0:0?
A: The nexus used to display array disks is "channel:target:lun." The Logical
Unit Number (LUN) is always "0." The channel and the target IDs are
necessary to identify array disks when dealing with SCSI devices.
When dealing with SAS devices, the array disk location is displayed as
"channel:target:enclosure." It is possible to have the enclosure value as non-
zero. If the enclosure has a non-zero value, then all three numbers (channel,
target, and enclosure) have to be included on the command line.
Q: Do I need to specify RAID type and size when creating virtual disk(s)?
A: No. The default RAID type is RAID 0. If RAID size is not provided, the
maximum size allowed for virtual disk is created. The mandatory fields
required to create virtual disks are the controller slot ID and the array disks.
Q: What is a hotspare (failover drive)?
A: A hotspare is an extra and unused disk drive that is part of an array disk
subsystem. A hotspare is always in standby mode. If a disk failure occurs, the
hotspare replaces the failed drive without interrupting the system.
Q: What is mr2kserv.exe?
A: This is a service needed to configure all LSI RAID controllers in Windows
PE. It provides Plug and Play support.
