Symmetrix Fibre Channel with Qlogic HBAs on UnixWare 7
Fabric Configurations
The kernel must be rebooted for any changes in the
/etc/conf/pack.d/qlc2200/space.c file to take effect. Verify that all
other variable in space.c are set in accordance with Other Driver
Variables on page 39, then rebuild the kernel and reboot.
Other Driver Variables Setup Checklist step 11b
Verify that the other variables in /etc/conf/pack.d/qlc2200/space.c are
set correctly.
After changes are made to the space.c, the kernel must be rebuild and
host rebooted.
The variable qlc2200_internal_timeout sets the timeout in case of a
link-down or Symmetrix off-line condition. Set this variable to 60
seconds to ensure proper fault tolerance:
ushort qlc2200_internal_timeout = 60;
After 60 seconds, mounted file systems will be disabled and all I/O to
the failed device will be terminated. Because of SCO memory
implementations with vxfs file systems, vxfs file systems could hang
if this setting is greater than 60 seconds. With very large
configurations, this variable may need to be set to 30 seconds.
Rebuilding the Kernel Setup Checklist step 11c
After verifying that all settings in /etc/conf/pack.d/qlc2200/space.c
are correct, save the file, then rebuild the kernel and reboot:
1. Type cd /etc/conf/bin ENTER.
2. Type
./idbuild -B ENTER.
3. Type
./idcpunix ENTER.
4. Reboot.
