Linux Operating System Issues; Hard-Disk Drive Display Omits Disk Listing At Installation When Multiple Scsi Disks Are Attached To System On Rhel4 U4 (6447738); Duplicate Devices Seen By Linux Os If External Raid Array Connects To Server Through Ultra320 Scsi (6220406) - Sun Microsystems Fire X4100 Product Notes

Linux Operating System Issues

This section describes known problems and associated workarounds on Sun Fire
X4100 and Sun Fire X4200 servers for RHEL operating system and the SLES.
Hard-Disk Drive Display Omits Disk Listing At
Installation When Multiple SCSI disks Are
Attached to System on RHEL4 U4 (6447738)
The hard-disk drive display omits a disk listing during installation if there are many
SCSI disks attached to a system. Not all disks are available during the installation.
In addition, the disk-drive display lists the wrong drive type after the installation.
Workaround
None. However, to display the omitted hard-disk drive, use one of the following
instructions:
During installation, disconnect all external storage devices except those devices
■
needed for disk initialization.
Perform manual disk-initialization after you reboot the system, when all disks are
■
available.
Duplicate Devices Seen by Linux OS if External
RAID Array Connects to Server Through Ultra320
SCSI (6220406)
If a RAID array is attached to the system using a Sun StorEdge PCI/PCI-X Single
Ultra320 SCSI host bus adapter (Ultra320 SCSI), you might see the following if you
enter the command, fdisk -l, depending on which Linux OS you are using:
Duplicate devices for each logical unit number (LUN) in the array
■
One device for multiple LUNs in the array
