OpenVMS The default value 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 controller software upgrade. Online controller software 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; Tru64 Tru64 has a 60 second timer for media command timeouts. In most cases, up to 5 retries can occur within the kernel's I/O stack, which results in a 5-6 minute window before I/O is returned to the file system. No changes should be made to any Tru64 settings when performing an online controller software upgrade. Online controller software upgrades are supported in Trucluster 4-node environments where the EVA is the cluster boot device. 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. 30 Pre-upgrade tasks

OpenVMS
The default value 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 controller
software upgrade.
Online controller software 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;
Tru64
Tru64 has a 60 second timer for media command timeouts. In most cases, up to 5 retries can occur
within the kernel's I/O stack, which results in a 5–6 minute window before I/O is returned to the
file system. No changes should be made to any Tru64 settings when performing an online controller
software upgrade.
Online controller software upgrades are supported in Trucluster 4–node environments where the
EVA is the cluster boot device.
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.
