2. The following information is needed from these listings for each Symmetrix logical device:
• Disk name (for example, /dev/sda).
• Device type (R1, R2, BCV, GK, or blank).
• Symmetrix serial number (for example, 2800340000), useful in matching the disk name
to the actual devices in the Symmetrix configuration downloaded by EMC support staff.
3. Use the symrdf command on each Symmetrix disk array (that is, from both the R1 and the
R2 side) to pair the logical device names for the R1 and R2 sides of each SRDF link:
# symrdf list
NOTE: The format of output varies depending on the Solutions Enabler version.
