◦ 100 is recommended if the line speed is from 100 Mb/s to 255 Mb/s.
◦ 256 is recommended if the line speed is 256 Mb/s and more.
This setting does not take effect on master journal groups. However, if the RAID Manager
horctakeover command is used to change a master journal group into a restore journal group,
this setting takes effect on the journal group.

Parity Group: Indicates the parity group where a journal volume belongs.◦

A consistency group number shown as [01], indicates that the multiple primary and
