Live Volume with Linux/UNIX
87 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
10.5.2 Existing Live Volumes created before SCOS 7.3
For existing Live Volumes created before SCOS 7.3, ensure that these volumes have an ALUA Optimized
status of No in DSM and are excluded from being upgraded to ALUA-optimized.
After SCOS is upgraded to 7.3, DSM displays a banner in the Live Volume tab indicating that there are
existing Live Volumes that can be optimized for ALUA. Select any Live Volume on the list to see the existing
ALUA Optimized status. See Figure 70.
Live Volume ALUA optimization banner and ALUA optimization status
Live Volumes created before SCOS 7.3 do not automatically become ALUA optimized. The storage
administrator must click the Update to ALUA Optimized link to initiate the optimization process. The link
opens a pop-up window that shows all Live Volumes that are eligible for optimization. See Figure 71. To
ensure Linux Live Volumes do not get ALUA optimized, unselect them from the list.
Note: By default, all eligible Live Volumes are selected. It is important to make sure the Linux Live Volumes
are unselected from the list. These Live Volumes will remain on the list and need to be unselected the next
time the storage administrator optimizes other Live Volumes.
