Shared disks not visible in SF Oracle RAC cluster
If the shared disks in /dev are not visible, perform the following tasks:
Make sure that all shared LUNs are discovered by the HBA and SCSI layer. This can be verified by running the ls -ltr command on any of the disks under /dev/*.
For example:
# ls -ltr /dev/disk_name
If all LUNs are not discovered by SCSI, the problem might be corrected by specifying dev_flags or default_dev_flags and max_luns parameters for the SCSI driver.
If the LUNs are not visible in /dev/* files, it may indicate a problem with SAN configuration or zoning.
