IT23358: IBM SP for VE Linux mount operations requires Linux guest VMs with all LVM Physical Volumes assigned to a Volume Group

APAR status

• Closed as program error.

Error description

• During a Linux mount operation the following error is shown:
  
  On the VE User Interface:
  WARNING ANS3141W Mounting the following devices failed:
   'lvm lvs -a --noheadings lvm2'.
  WARNING ANS3150W The block device '/dev/sdb' of type
   'LVM2_member' failed to mount. Volume group "lvm2" not found.
   Cannot process volume group lvm2 '
  ERROR ANS3101E The mount operation for virtual machine 'vm01'
   failed with rc = 5. For more details, check the Recovery Agent
   logs.
  ERROR ANS3174E (RC6841) The virtual machine mount failed.
  
  On the File Restore User Interface:
  "An error occurred while loading the backup. If the problem
   persists, contact your administrator"
  The frapi.log file shows:
  <log4j:message><![CDATA[An error occurred while loading the
   backup. If the problem persists, contact your administrator.]]>
   </log4j:message>
  ...
  <log4j:data name="action" value="MountLoad"/>
  ...
  <tsm:returnCode>6841</tsm:returnCode>
  
  Customer/L2 Diagnostics :
  A service trace of the Linux mount proxy client shows the
   following errors :
  
    Volume group "lvm2" not found
    Cannot process volume group lvm2
  
  The error is logged because the Linux guest VM at the time of
  the backup contains one or more LVM Physical Volumes without
  a Volume Group assigned.
  
  To verify this run the 'lvm pvs' command on the guest VM and
  check if the Volume Group is not empty for each Physical Volumes
  
  As example the following command shows 2 Physical Volumes,
  /dev/sdb and /dev/sdc, without a Volume Group assigned.
  >lvm pvs
    PV            VG       Fmt   Attr    PSize     Pfree
    /dev/sda1  vg_01   lvm2  a--u   2.45g      0
    /dev/sda2  vg_02   lvm2  a--u   5.22g      0
    /dev/sdb                lvm2  ----    55.00m   55.00m
    /dev/sdc                lvm2  ----    55.00m   55.00m
  
  Initial Impact: Low
  Additional Keywords: SP TSM VE FLR
  
  Versions Affected:
  IBM Spectrum Protect for Virtual Environments V7.1 and V8.1
  

Local fix

• Ensure that a Volume Group is assigned to each Physical Volumes
  of each Linux guest VM used for IBM Spectrum for Virtual
  Environments Linux mount operations.

• After the fix  Data Protection for VMware Mount proxy
  do not fails if mounted physical volume has no
  assigned volume group.
