IT15105: SRA PROBE STAYS IN "IN PROGRESS" STATE DUE TO LINUX COMMAND "LVMPVS" HANGING DURING PROBE.

APAR status

• Closed as Vendor Solution.

Error description

• The logical volume manager (lvm) commands on Linux may hang for
  a variety of reasons, e.g. if a disk is suspended, recreatable
  by running "dmsetup suspend diskname" command. One of the
  commands that may hang is the "lvm pvs" command.
  
  When a Storage Resource agent is deployed on a Linux host, it
  invokes several Linux commands, including "lvm pvs." When this
  happens, the Storage Resource agent probe will hang at the point
  that the lvm command did. On the IBM Spectrum Control web UI,
  the Storage Resource agent probe will remain in "In Progress"
  state and doesn't give any indication that the probe has hung.

Problem summary

Problem conclusion

Temporary fix

Comments

• IBM Spectrum Control and the Storage Resource agent (SRA) cannot
  fix the cause of the "lvm pvs" hanging situation.
  
  To verify that this is the situation causing the hang, view the
  SRA trace log on the SRA Deployment and verify that the last
  command was an LVM one.   To recover from this:
  
  - Kill the hung SRA process
  - Kill the hung LVM command
  - From a command line, retry the LVM command and verify that it
  runs successfully. If it does not, use the LVM documentation to
  repair the LVM so that it does.
  - Restart the SRA
