I think I am hitting a major issue here with a mirrored volume in RVG.SRL is supposed to provide the DRL functionality . Hence DRL logging is explicitly disabled when a volume is added to RVG. However my testing shows that DRL is not working and in t...

Infoscale 8.0 on Redhat 8.7I am observing that even when SRL is not overflowing , the primary and second volumes are writing into DCM bitmaps which is not how it should work.DCM should only be used during an initial sync or resync or SRL overflow an...

Using tradition 3rd mirror break off snapshot using vxassist, when multiple volumes are specified on the snapshot command, all the volumes are split atomically and all the volumes are split exactly at same point in time.This is a very very useful fea...

Do you think DRL style recovery (only dirty regions synced up) will happen if I simulate an actual crash scenario of the Linux host? -- Can you pls confirm as per design an unclean server shutdown/crash will NOT do a full resync of plexes?I am not su...

Mirrored volume can use DRL feature by either using a log-plex OR using DCO for DRL logging.So, when using DCO for DRL there WILL NOT be a separate log plex. But DRL will be included in the DCO maps.Pls see below the steps I followed to create the ...

thanks for verifying that vxsnap option works with "infrontof" on VVR secondary volumes.So are you suggesting that:1) If I want to use cascaded snaps on VVR secondary I should use "vxsnap" command.In all other type of snaps (space optimized, instant...

DRL not working on mirrored volumes in VVR - RVG (Mirrored volume doing full resync of plexes)

Does Infoscale Storage (VVR) support cascaded space-optimized snapshot?

Does VVR support cascaded space-optimized snapshot?

Infoscale 8.0 VVR (volume replicator) once DCM mode activates it never stops updating DCM bitmaps

instant snapshot (vxsnap) - multiple volumes - are the snapshots consistent between each other ?
