Error Message

# vxdg import rcbdg
VxVM vxdg ERROR V-5-1-10978 Disk group rcbdg: import failed:
No valid disk found containing disk group

The hostid field will be populated with the name of the server where the diskgroup was last imported.  This field will be erased upon a logical export.  Typically, when a system crashes, this field is left populated and will produce the error above on a subsequent import.

Use the -C switch at the command line to clear this field.

  

 

Applies To

This will apply to any non-shared diskgroup in any version of standalone Voume Manager environment (standalone server or failover cluster) on any supported Operating System.

See message in ERROR section below.  While the issue discussed here applies to stand-alone Volume Manager (stand-alone or failover cluster), the import locking method used in a Clustered Volume Manager environment is similar (CVM, CFS or RAC).  Stand-alone Volume Manager (non-shared diskgrup) will use the field of "hostid" while Clustered Volume Manager (shared diskgroups) will use field of "clustid" (for a shared disk group).   See the Volume Manager Admistator's Guide for more information on import locking.   In other words, a stand-alone Volume Manager environment (stad-alone server or failover cluster), a non-shared diskgroup will use the field of "hostid" for the import locking mechanism.   When any error is encountered importing a disk group (and this will apply in all enviroments), the first steps in troubleshooting are to make sure that all disks have an online status (error or online invalid is not good) and to validate the deported state of the diskgroup (vxdisk -o alldgs list).   For example: # vxdisk -o alldgs list
