Description

Error Message

# vxdctl enable
VxVM vxconfigd ERROR V-5-1-1589 enable failed: Error in disk group configuration copies
Kernel and on-disk configurations don't match; transactions are disabled

Cause

Code changes introduced in VxVM 5.1 SP1 does not correctly handle BCV devices in NR state. As a result, subsequent restart of vxconfigd or device rescan causes vxconfigd not to start in enable mode.

Resolution

Problem reproduction

1. VxVM version affected by this issue

5.1SP1 to 5.1SP1RP1P1HF2

# modinfo | grep -i vx
28  1355760  50c18 288   1  vxdmp (VxVM 5.1SP1RP1P1HF2 DMP Driver)
30 7be00000 21a918 289   1  vxio (VxVM 5.1SP1RP1P1HF2 I/O driver)
32  139f9e8   1198 290   1  vxspec (VxVM 5.1SP1RP1P1HF2 control/sta)

2. Verify vxconfigd daemon mode

#vxdctl mode
mode: enabled

3. Change BCV device state from READY to NOT READY state

# symdev  -sid 822 not_ready  0052
Execute a 'Not Ready' Device operation for device '0052' (y/[n]) ? y
'Not Ready' Device operation successfully completed for the device.

  # symdev  -sid 822 not_ready  0053
Execute a 'Not Ready' Device operation for device '0053' (y/[n]) ? y
'Not Ready' Device operation successfully completed for the device.

  # symdev  -sid 822 not_ready  0054
Execute a 'Not Ready' Device operation for device '0054' (y/[n]) ? y 'Not Ready' Device operation successfully completed for the device.

  # symdev  -sid 822 not_ready  0055
Execute a 'Not Ready' Device operation for device '0055' (y/[n]) ? y 'Not Ready' Device operation successfully completed for the device.

4. Re-scan devices under VxVM control. It will fail with following error

#vxdctl enable
VxVM vxconfigd ERROR V-5-1-1589 enable failed: Error in disk group configuration copies
Kernel and on-disk configurations don't match; transactions are disabled

  #vxdctl mode
mode: disabled

 

 

Solution

This issue will be fixed in subsequent hotfix release on top of VxVM 5.1 SP1 RP1 HF2.

Please contact Veritas Technical Support to obtain this patch.
