- Appendix: RAID Description
Corrective
Action:
The error message is displayed when the Linux Small Computer System Interface (SCSI) mid-
layer asks for physical disk cache settings. The controller firmware manages the virtual disk
cache settings on a per controller and a per virtual disk basis, so the firmware does not
respond to this command. The Linux SCSI mid-layer assumes that the virtual disk's cache
policy is Write-Through. SDB is the device node for a virtual disk. This value changes for each
virtual disk.
See the topic Write-Back And Write-Through for more information about Write-Through cache.
Except for this message, there is no effect of this behavior on normal operation. The cache
policy of the virtual disk and the I/O throughput are not affected by this message. The cache
policy settings for the PERC SAS RAID system remain unchanged.
Driver Does Not Auto-Build Into New Kernel
Issue: Driver does not auto-build into new kernel after customer updates.
Corrective
Action:
This error is a generic problem for Dynamic Kernel Module Support (DKMS) and applies to all
DKMS-enabled driver packages. This issue occurs when you perform the following steps:
1. Install a DKMS-enabled driver package.
2. Run up2date or a similar tool to upgrade the kernel to the latest version.
3. Reboot to the new kernel.
The driver running in the new kernel is the native driver of the new kernel. The driver package
you installed previously in the new kernel does not take effect in the new kernel:
1. Type: dkms build –m <module_name> –v <module version> –k
<kernel version>.
2. Type: dkms install –m <module_name> –v <module version> –k
<kernel version>.
3. Type the following to check whether the driver is successfully installed in the new kernel:
DKMS. The following details appear:
<driver name>, <driver version>, <new kernel version>:
installed
Unable To Register SCSI Device Error Message
Error:
smartd[smartd[2338] Device: /dev/sda, Bad IEC (SMART) mode
page, err=-5, skip device smartd[2338] Unable to register SCSI
device /dev/sda at line 1 of file /etc/smartd.conf
.
Corrective
Action:
This is a known issue. An unsupported command is entered through the user application. User
applications attempt to direct Command Descriptor Blocks to RAID volumes. The error
message does not affect the feature functionality. The Mode Sense/Select command is
supported by firmware on the controller. However, the Linux kernel daemon issues the
command to the virtual disk instead of to the driver IOCTL node. This action is not supported.
