Applies to

  • MetroCluster IP
  • Single drive reporting messages during SCRUB
  • The drive reporting the messages is not local to the node.

Issue

  • Event Message System (EMS) messages reported. Example:

[Node_name: config_thread: raid.rg.scrub.summary.lw:notice]: Scrub found 7 RAID write signature inconsistencies in /aggr/plex1/rg1.
[Node_name: config_thread: callhome.dsk.scrub.parity:alert]: Call home for DISK SCRUB PARITY INCONSISTENCY

  • No 'scsi.cmd.checkCondition' or 'disk.ioRecoveredError' errors can be found in the EMS.
  • All the errors repaired, for the single impacted drive. Example:

[Node_name: raidio_thread: raid_rg_readerr_repair_data_1:debug]: params: {'owner': '', 'disk_info': 'Disk /aggr/plex1/rg1/0m.i2.2L51P1 Shelf 12 Bay 17 [NETAPP   X357_SLBPE3T8ATE NA51] S/N [XXXXXXXXXXXXX] UID [...]', 'blockNum': '243299396', 'vbn': '11452396996', 'shelf': '12', 'bay': '17', 'vendor': 'NETAPP  ', 'model': 'X357_SLBPE3T8ATE', 'firmware_revision': 'NA51', 'serialno': 'XXXXXXXXXXXXX', 'disk_type': '5', 'disk_rpm': 'N/A', 'carrier': '', 'site': 'Remote'}

  • The reported aggregate is online and it doesn't have any failed (broken) disks. Example:

::> storage aggregate show-status -aggregate aggr
Owner Node: Node_name 
   Aggregate: aggr (online, raid_dp, hybrid) (block checksums)
     Plex: /aggr/plex1 (online, normal, active, pool0)
         RAID Group /aggr/plex1/rg1 (normal, block checksums)
