x  Import_FNM00104600114_migrate_xxx          Error           block


Hvis du holder markøren over det røde X, i ovenstående fejl, vises flere detaljer:

"The import session failed due to a non-recoverable error.  Go to session properties dialog to check health details and resolution steps in GUI or use UEMCLI command  import/session/element show -detail to check session health details and resolution steps."    


UEMCLI-outputtet med sessionsoplysningerne viser lignende meddelelser:

spa:~>uemcli /import/session show -detail
1:    ID              = import_65548
      Name            = Import_ABCD1234567890_101_20160915160406.767527+000
      Session type    = block
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable error. For Block import session non-recoverable error details, check session element's health details and resolution steps."
      State           = Error  ---output abridged----


UEMCLI-outputtet for sessionselementet for ovenstående importsessions-id:

Eksempel 1:

spa:~>uemcli /import/session/element -importId import_65548 show -detail
1:    Source system   = RS_65560
      Source resource = LUN 101
      Target resource = sv_11
      Health state    = Major failure (20)
      Health details  = "Element import session related Sancopy session ran into error: 0x712A8021: The destination device could not be found. This is probably due to incorrect zoning on the switch or the device is not in the correct storage group. (WWN). This can be due to FC Zoning or iSCSI Connection configuration between VNX and Unity arrays. Please follow documentation to configure connectivity between all SP pairs between VNX and Unity system. Once FC/iSCSI connection configuration is validated, please run 'Verify and Update' operation for Remote System connection to VNX to discover/update all configuration changes. Then issue resume operation on the import session to recover session from error state."


Eksempel 2:

spb:~> uemcli /import/session/element -importId import_65600 show -detail
2:    Source system   = RS_65596
      Source resource = block_1
      Target resource = sv_79
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."

Cause

A "Non-recoverable error" i en blokimportsession kan have forskellige årsager og er muligvis ikke altid permanent. Undersøgelse af elementdetaljerne hjælper med at identificere årsagen til problemet. Potentielle årsager omfatter:

  • iSCSI-forbindelsesproblemer, som kan løses og tillade, at sessionen genstartes
  • Problemer på kilde-VNX-matrixet, f.eks. manglende LUN i en konsistensgruppe, som kan kræve annullering af sessionen
  • Kilde-LUN er utilgængelig på grund af sletning eller manglende opdateringer på Unity-systemet, hvilket også kræver, at sessionen annulleres

Undersøgelse af elementdetaljerne kan hjælpe med at fastslå årsagen og tage passende handlinger for at løse eller annullere den mislykkede session.

Resolution

Som beskrevet ovenfor kan der være forskellige problemer, der fører til en 'Non-recoverable error' for en blokimportsession.
Unisphere (UI) giver muligvis ikke nok oplysninger til at løse problemet. Det anbefales at bruge outputtet fra UEMCLI session elementet for at fejlfinde og løse problemet.

Importsessionen mislykkedes med "Ikke-genoprettelig fejl":
1. Fra UEMCLI skal du bestemme importsessions-id'et:

spb:~> uemcli /import/session/block show -detail
1:    ID                           = import_65600
      Name                         = Import_ABCD1234567890_migrate_20161027142745.428999+000
      Session type                 = block
      Health state                 = Critical failure (25)


2. Få vist oplysninger om importsessionselementet for importsessions-id'et:

spb:~> uemcli /import/session/element -importId import_65600 show -detail
1:    Source system   = RS_65596
      Source resource = block_1
      Target resource = sv_79
      Health state    = Critical failure (25)
      Health details  = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."


3. Følg rådene i outputtet "Tilstandsoplysninger" for at fejlfinde og løse problemet med importsessionen.
Seddel: For at fortsætte skal du genoptage sessionen under "Flere handlinger" i brugergrænsefladen.
