Problem: If you use Oracle RAC with Solaris Volume Manager for shared file systems, you might see a message that volumes are not available.
Solution: In response to this issue, you can configure the rac_maxdevretry parameter in the /etc/opt/SUNWsamfs/defaults.conf file. By default, the rac_maxdevretry variable is set to 150 (5 minutes).
The items to take in account for adjusting this variable include:
Number of nodes in the cluster
Number of physical LUNs
Number of Solaris Volume Manager disk groups
Speed of array topology 1G/2G/4G
In the following example /etc/opt/SUNWsamfs/defaults.conf file, the time is shortened to 90 seconds (3 minutes).
trace all = on sam-sharefsd.options = all sam-fsd.size = 10M sam-sharefsd.size = 10M endtrace rac_maxdevretry = 90
This change was based on the following environment:
Nodes - 8
Physical LUNs - 32 Shared Physical LUNS with 4G Fibre Channel
Solaris Volume Manager disk groups - 1
Shared file systems - 13
An example of this setting is included in the /etc/opt/SUNWsamfs/examples/defaults.conf file.
