Symptoms

Systemkonfiguration, systemkapacitet, systemadvarsler og statistikker over systemydeevne genereres af GW, når et system er konfigureret til at sende CloudIQ-egenskaber og statistiske data.

Oprettelsen af en af de fire pakker kan som standard ikke stoppes manuelt.

GW kan ikke indsamle mængdestatistikker og generere ydeevnepakken på grund af et problem med fortolkningen af RestAPI-svar mellem den og MDM.
Se afsnittet Yderligere oplysninger for at få flere oplysninger om flowet for dataindsamling og generering.

Følgende undtagelsesfejl findes i GW scaleio-trace.log filerne:

Cause

PowerFlex understøtter SCSI-2-reservation og et undersæt af SCSI-3-reservationskommandoer. SCSI-reservationskommandoer (nulstil, reserver, frigiv, læs) sendes af SDC'er til MDM, som derefter opdaterer SDS erne.
Når der er foretaget en SCSI-3-reservation på en diskenhed, kalder RestAPI fra GW til MDM for at læse diskenhedsstatistikken og mislykkes derefter med fejlen nævnt ovenfor - Dårligt tal: 3.

GW fejlfortolker SCSI-reservationstypen og får ikke RestAPI-kaldet til at vende tilbage fra MDM.
I/O og reservationen på PowerFlex-siden fungerer som forventet.

Hvordan valideres SCSI-reservationsoplysninger i get_info?

$ awk 'BEGIN { printf "%-15s %-15s %s\n", "Volume_ID", "Volume_Name", "SCSI_Reservation"; printf "%-15s %-15s %s\n", "---------", "-----------", "----------------" }; /: ID:/ { volume_id = $2; volume_name = $3 } / SCSI-reserver-key:/ { scsi_reserv = $1; if (scsi_reserv == "scsi2-reserved:3"){ printf "%-15s %-15s %-15s %s\n", volume_id, volume_name, scsi_reserv, "<<< SCSI-3 !!!" } else{ printf "%-15s %-15s %s\n", volume_id, volume_name, scsi_reserv } }' getInfoDump/mdm/sdbg_out.txt | column -t
Volume_ID                Volume_Name          SCSI_Reservation
---------                -----------          ----------------
ID:0x2fad5f7f00000000    Name:vol1-sp1-PD1    scsi2-reserved:0

Hvordan valideres SCSI-reservationsoplysninger på et live-system?

$ cat > script
c mdm
dumpallscreens
disconnect
exit
^D
$ /opt/emc/scaleio/sds/diag/sdbg script > sdbg_out.txt
$ awk 'BEGIN { printf "%-15s %-15s %s\n", "Volume_ID", "Volume_Name", "SCSI_Reservation"; printf "%-15s %-15s %s\n", "---------", "-----------", "----------------" }; /: ID:/ { volume_id = $2; volume_name = $3 } / SCSI-reserver-key:/ { scsi_reserv = $1; if (scsi_reserv == "scsi2-reserved:3"){ printf "%-15s %-15s %-15s %s\n", volume_id, volume_name, scsi_reserv, "<<< SCSI-3 !!!" } else{ printf "%-15s %-15s %s\n", volume_id, volume_name, scsi_reserv } }' sdbg_out.txt | column -t

Volume_ID                Volume_Name          SCSI_Reservation
---------                -----------          ----------------
ID:0x2fae49da00000001    Name:vol1-sp1-PD1    scsi2-reserved:0
ID:0x2fad5fcb00000002    Name:vol2-sp1-PD1    scsi2-reserved:3  <<<  SCSI-3  !!!
ID:0x2fad5fcc00000003    Name:vol3-sp1-PD1    scsi2-reserved:3  <<<  SCSI-3  !!!
ID:0x2fa9dd3d00000004    Name:vol4-sp1-PD1    scsi2-reserved:0

Resolution

Da SCSI-reservationen angives af klient- og programsiden, er den eneste løsning at frigøre reservationen fra diskenheden.

Additional Information

Flowet til indsamling og oprettelse af ydeevnebundtfilen består af to separate processer:

Ikonet  Første proces  Er aktiveret  Hver 5. sek.  Og sender en anmodning om statistik fra MDM og gemmer svaret på en akkumuleret måde.

Ikonet  Anden proces  Er aktiveret  Hvert 5. minut  Hvor den beregner deltaerne og komprimerer dataene til en .zip fil inde i mappen /opt/emc/scaleio/gateway/temp.
