Introduction to the Sun Blade Storage Module M2
Maintaining the Sun Blade Storage Module M2
Enabling MPXIO manually on a newly installed system with a Sun Storage 6Gb SAS REM HBA (SGX-SAS6-REM-Z) will result in error messages. When stmsboot -e is manually run to enable MPxIO, the following harmless messages will print during the booting process:
Error: Your root device is not mapped.
In order to prevent or eliminate the message, perform the following workaround.
Login as root user on the system displaying the message.
Run stmsboot -e to enable multipathing. For example:
host-1-root@[/]>stmsboot -e WARNING: stmsboot operates on each supported multipath-capable controller detected in a host. In your system, these controllers are /pci@1f,700000/pci@0/pci@2/pci@0/pci@8/LSILogic,sas@1 /pci@1f,700000/pci@0/pci@9/LSI,sas@0/iport@f0 If you do NOT wish to operate on these controllers, please quit stmsboot and re-invoke with -D { fp | mpt | mpt_sas} to specify which controllers you wish to modify your multipathing configuration for. Do you wish to continue? [y/n] (default: y) y
Reboot the system. For example:
host-1-root@[/]>reboot
Login as root user and run stmsboot -e again. Answer y to the Do you wish to continue prompt. For example:
host-1-root@[/]>stmsboot -e WARNING: stmsboot operates on each supported multipath-capable controller detected in a host. In your system, these controllers are /pci@1f,700000/pci@0/pci@2/pci@0/pci@8/LSILogic,sas@1 /pci@1f,700000/pci@0/pci@9/LSI,sas@0/iport@f0 If you do NOT wish to operate on these controllers, please quit stmsboot and re-invoke with -D { fp | mpt | mpt_sas} to specify which controllers you wish to modify your multipathing configuration for. Do you wish to continue? [y/n] (default: y) y STMS is already enabled. No changes or reboots needed
The system tells you that STMS is already enabled and no reboot is necessary. A reboot is still required to ensure the error message will be cleared.
Reboot the system. For example:
host-1-root@[/]>reboot
Note - This issue is fixed in the Solaris 10 5/10 OS.
