fcp_offline_delay is introduced from v1.110 fcp in S10U3. You are using
1.109, so you need to get a newer patch.

We are hoping to increase the fibre channel failover timeout from the default of twenty seconds to 30 seconds to accomadate a controller failover on our SAN. We are running Solaris 10 which is patched to Dec 2006, a McData switch and a dual port QLogic 2342 card. We have port down retry and login retry counts set to 60 in the /kernel/drv/qlc.conf file and in the bios of the QLogic card but it appears that a system variable is overidding the qlc.conf file information. When we attempt to failover a SAN controller, the ports are flagged down after twenty seconds.
Based on this thread, the way to increase this time out value may be via the fcp_offline_delay variable. The adb -kw command followed by fcp_offline_delay /D returns the unknown symbol name information.
# adb -kw
physmem 1f944
fp_offline_ticker /D
fp_offline_ticker:
fp_offline_ticker: 90
fcp_offline_delay /D
adb: failed to dereference symbol: unknown symbol name
Here are the current versions of the SFS software on the machine.
The drivers appear to be newer than the ones listed in this thread.
Please correct me if I am wrong.

Is there a procedure to introduce the new variable to the kernel and increase the timeout value?
Thanks in advance for any help.
