Symptoms
從 Magnolia 代碼 (10.2) 開始的新 SRDF 群組預設會啟用 RDFA 自動復原功能。您可以使用以下命令為 RDFG 停用此功能:
symrdf -sid xxxx -rdfg ## set rdfa -autostart off
關閉此功能後,重新開啟此功能的命令似乎無法運作。例如:
C:\>symrdf -sid xxxx -rdfg 15 set rdfa -autostart on -nop
An RDF Set 'Attributes' operation execution is in
progress for RDF group 15. Please wait...
SRDF/A Set Autostart (xxxx,0015).................................Started.
SRDF/A Set Autostart (xxxx,0015).................................Done.
The RDF Set 'Attributes' operation successfully executed
for RDF group 15.

此行為為設計運作方式。此功能停用後,只能透過重新啟動 SRDF/A 工作階段來重新啟用。在 SRDF/A 工作階段重新啟動之前,自動復原會保持非使用中狀態,即使已啟用自動啟動。因此,您必須掛起然後恢復複製才能看到組的此值更改。
Resolution
因應措施:您可以使用下列命令重新啟用 RDFA 自動復原功能:
symrdf -sid xxxx -rdfg 15 set rdfa -autostart on -nop
啟用此功能後,您必須先暫停再繼續複寫,才能重新啟動此 SRDF 群組的自動復原功能:
C:\>symrdf -sid xxxx -f rdfg15.txt -rdfg 15 suspend -nop An RDF 'Suspend' operation execution is in progress for device file 'rdfg15.txt'. Please wait... Suspend RDF link(s) for device(s) in (xxxx,0015).................Started. Suspend RDF link(s) for device(s) in (xxxx,0015).................Done. The RDF 'Suspend' operation successfully executed for device file 'rdfg15.txt'. C:\>symrdf -sid xxxx -f rdfg15.txt -rdfg 15 establish -nop An RDF 'Incremental Establish' operation execution is in progress for device file 'rdfg15.txt'. Please wait... Suspend RDF link(s) for device(s) in (xxxx,0015).................Done. Resume RDF link(s) for device(s) in (xxxx,0015)..................Started. Resume RDF link(s) for device(s) in (2206,0015)..................Done. The RDF 'Incremental Establish' operation successfully initiated for device file 'rdfg15.txt'.
現在,當您查詢群組時,它會顯示 RDFA 自動復原已啟用:
