Openvms; Solaris; Checking Or Changing Timeouts; Vmware - HP 6400/8400 Software Manual

OpenVMS

The limit for LUN timeout is 120 seconds.
NOTE:
OpenVMS handles the controller reboot seen at the conclusion of the firmware update process. Disks
on the controller display a Mount Verify status during the controller reboot but regain Mounted status
and resume I/O operations upon the completion of the controller reboot. No changes need to be
made to any OpenVMS default settings when performing an online firmware upgrade.
Online controller firmware upgrades are supported in OpenVMS cluster environments where the EVA
is the cluster boot device.

Solaris

Solaris supports online controller upgrades with the following driver timeouts:
• Sun Drivers (qlc or emlxs): 60 seconds
• QLogic (qla2300): 60 seconds
• Emulex (lpfc): 60 seconds

Checking or changing timeouts

For Sun drivers, add the following lines to /etc/system file:
set sd:sd_io_time = 60
set ssd:ssd_io_time = 60
For QLogic, edit the /kernel/drv/qla2300.conf file and change the
hbax-link-down-timeout value to 60 as follows:
hba0-link-down-timeout=60;
For Emulex, edit the /kernel/drv/lpfc.conf file and change the linkdown-tmo value to 60
as follows:
linkdown-tmo=60;

VMware

VMware ESX (Hypervisor) does not time I/O for a guest operating system. Thus the SCSI timeouts on
commands issued by each VMware guest (Linux, Windows, Solaris) are those provided for these
systems.
