When using mirroring among servers, this message may be output during node stop after upgrading the scsi-target-utils package. For the resolution, see "8.9 Upgrading scsi-target-utils Package [4.3A40 or later] [RHEL6]."
WARNING: sfdsk: failed to abort I/O requests on disk:device info : devno(maj,min)=p_devno(p_maj,p_min)
devname=pdev
error info : errno=errno
Explanation
The request to cancel I/O requests on the physical device indicated in device info (an ioctl request for the mphd or mplb driver) ended abnormally.
Resolution
Collect investigation material and contact field engineers.
WARNING: sfdsk: hook for device is not GDS entry.
Explanation
Inconsistency was found in management information of disks registered with GDS, but it does not affect the operation.
Resolution
No resolution is required.
WARNING: access protection of physical special files disabled, major=major
Explanation
Accessing physical special files of the device for the major number major cannot be restrained due to unsuccessful memory allocation.
Resolution
Be careful not to access physical special files directly.
To restrain access physical special files, check whether you have sufficient memory or swap area, and then reboot the system after performing the procedure if necessary.
WARNING: sdxfunc: no enough address space, osfunc=osfunc, errno=errno
Explanation
Memory allocation failed.
Resolution
Check whether you have sufficient memory or swap area. If not, expand it and reboot the system.
WARNING: sfdsksys: cannot get device identifier, details
Explanation
Could not get the disk device identifier. Thus, operations such as setting or canceling the system disk mirroring, or swapping the disk cannot be performed.
Resolution
Collect investigation material and contact field engineers.
WARNING: sfdsksys: illegal disk specific informationExplanation
The disk specific information of the root class that GDS registered to NVRAM (non-volatile memory) of the server itself is invalid.
If this message is output, the system may not be started.
This error occurs when the patch for PH06344 is applied without canceling the system disk mirroring in the environment where the system disk mirroring is performed on a VMware guest by using virtual disk (VMDK) or RDM in virtual compatible mode.
Resolution
Cancel the system disk mirroring once, and set it again.
By this operation, the appropriate disk specific information is registered to NVRAM.
