Symptoms

Instant Access (IA)-hersteltaak wordt niet voltooid met fout:

Reached the maximum number of instant access sessions that are allowed on a Data Domain system.

Cause

Het Data Domain-object in Avamar heeft slechts "1" stream die is geconfigureerd voor directe toegang.

Resolution

  1. Controleer de Data Domain-versie. Als de Data Domain-versie ouder is dan 6.0, is slechts één Instant Access-stream toegestaan. Anders kunnen Instant Access-streams worden ingesteld tot 32.
  2. Meld u aan bij de Avamar-server als beheerder en voer de volgende opdracht uit:
ddrmaint read-ddr-info --format=full
admin@av-server:~/>: ddrmaint read-ddr-info --format=full

admin@av-server:~/>:
  1. Controleer de waarden van de Instant Access Limit-vlag:
mccli dd show-prop --xml | grep InstantAccessLimit
admin@av-server:~/>: mccli dd show-prop --xml | grep InstantAccessLimit
      <InstantAccessLimit>10</InstantAccessLimit>
admin@av-server:~/>:
  1. Controleer of Directe toegang herstellen is toegestaan in mcserver.xml:
grep "ddr_instant_access_enabled" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
admin@av-server:~/>: grep "ddr_instant_access_enabled" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml              
              <entry key="ddr_instant_access_enabled" value="true" />
admin@av-server:~/>:
  1. Controleer of de wijziging van de Instant Access-limiet is toegestaan in mcserver.xml:
grep "ddr_can_modify_ir_limit" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
admin@av-server:~/>: grep "ddr_can_modify_ir_limit" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml              
              <entry key="ddr_can_modify_ir_limit" value="false" />
admin@av-server:~/>:
  1. Maak een back-up van de mcserver.xml bestand:
cp -p /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml-`date -I`.bkp
admin@av-server:~/>: cp -p /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml-`date -I`.bkp
admin@av-server:~/>: ls -ltrh /usr/local/avamar/var/mc/server_data/prefs/*mcserver.xml*
-rw-r----- 1 admin admin 59K Aug 13 09:21 /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
-rw-r----- 1 admin admin 59K Aug 13 09:21 /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml-2021-09-30.bkp
admin@av-server:~/>:
  1. Bewerk de mcserver.xml Gebruik VI en wijzig de parameterwaarde hieronder:
Van:  
<entry key="ddr_can_modify_ir_limit" value="false" />
naar: 
<entry key="ddr_can_modify_ir_limit" value="true" />
  1. Sla de wijziging op en controleer of de wijziging is gelukt.
grep "ddr_can_modify_ir_limit" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
admin@av-server:~/>: grep "ddr_can_modify_ir_limit" /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
              <entry key="ddr_can_modify_ir_limit" value="true" />
admin@av-server:~/>:
  1. Start de Management Console Service (MCS) opnieuw:
mcserver.sh --restart --v --force
  1. Bewerk Data Domain vanuit de Avamar gebruikersinterface (AUI), Avamar Administrator console of via mccli-opdracht.
  2. Controleer of de waarde is veranderd:
mccli dd show-prop --xml | grep InstantAccessLimit
admin@av-server:~/>: mccli dd show-prop --xml | grep InstantAccessLimit   
      <InstantAccessLimit>32</InstantAccessLimit>
admin@av-server:~/>:    
  1. Start IA-hersteltaken om te controleren of meerdere IA's nu zijn toegestaan.
  2. Hervat de back-upplanningsservice en controleer of alle services actief en ingeschakeld zijn:
dpnctl start sched
dpnctl status
admin@av-server:~/>: dpnctl start sched
Identity added: /home/admin/.ssh/admin_key (/home/admin/.ssh/admin_key)
