Tips and Tricks

MultiPathMultiPathTips and Tricks

� General Recommendations for MultiPath� General Recommendations for MultiPath� Do not connect tape devices to FC zones which uses MultiPath – better use a separate HBA

for backup devices

� Do not establish multiple connections to one target before MultiPath installation� Do not establish multiple connections to one target before MultiPath installation

� HBA Settings� All settings are storage specific, there are no MultiPath specific settings� All settings are storage specific, there are no MultiPath specific settings

� Check presence and status of all MultiPath Groups� MultiPath status must show Active / Standby� MultiPath status must show Active / Standby� Check Acknowledge Configuration to enable the monitoring of missing paths

� Configure DuplexWrite first� Configure DuplexWrite first� Install DDM� Build all DuplexWrite groups and start recovery� ...configure your system and applications� ...configure your system and applications

� HBA Settings� All settings are storage specific� All settings are storage specific

� No special settings for DuplexWrite, use standard (or MultiPath) settings

� Check presence and status of all DuplexWrite groups� Check presence and status of all DuplexWrite groups� DuplexWrite status must show Online for all (partner) disks

� Be careful using Disk Administrator� Be careful using Disk Administrator� Never delete a COD partition, delete DuplexWrite group first
