vicfg-mpath35 - configure multipath settings for Fibre Channel or iSCSI LUNs

SYNOPSIS vicfg-mpath35 [OPTIONS] DESCRIPTIONvicfg-mpath35 provides an interface to configure multipath settings for Fibre Channel or iSCSI LUNs on ESX/ESXi version 3.5 hosts. Use vicfg-mpath for ESX/ESXi 4.0 and later hosts. OPTIONS--helpPrints a help message for each command-specific and each connection option. Calling the command with no arguments or with --help has the same effect. --list | -lLists all LUNs and the paths to these LUNs through adapters on the system. For each LUN, the command displays the type, internal name, console name, size, and paths, and the policy used for path selection. --policy | -pSets the policy for a given LUN to one of "mru", "rr", or "fixed". Most Recently Used (mru) selects the path most recently used to send I/O to a device. Round Robin (rr) rotates through all available paths. Fixed (fixed) uses only the active path. This option requires that you also specify the --lun option. --state | -sSets the state of a given LUN path …

Which ESX log file

Which ESX log file

• Vmkernel – /var/log/vmkernel – records activities related to the virtual machines and ESX server. • Vmkernel Warnings – /var/log/vmkwarning – This log is a copy of everything marked as a warning or higher severity from vmkernel log. It is much easier to look through this for warnings and errors, instead of filtering through the full information in the vmkernel logs. • Vmkernel Summary – /var/log/vmksummary – Used to determine uptime and availability statistics for ESX Server; human-readable summary found in /var/log/vmksummary.txt • ESX Server host agent log – /var/log/vmware/hostd.log – Contains information on the agent that manages and configures the ESX Server host and its virtual machines (Search the file date/time stamps to find the log file it is currently outputting to). • Service Console – /var/log/messages – This log is the log from the Linux kernel (service console), which is generally only potentially useful in the case of a host hang, crash,authentication issue, or 3rd party…
