B firmwareDownload -n Disables auto commit mode. When auto commit mode is disabled, the firmwareCommit command must be executed manually to propagate the downloaded image to both partitions of the storage device. host Specify a valid FTP or SSH server name or IP address. IPV4 and IPv6 addresses are supported. The firmware is downloaded from the specified host. If a host is not specified, the firmware is considered accessible on a local directory. To mention an FTP server by name, a DNS server must first be set up with the dnsConfig command. If DNS is enabled and a server name is specified, firmwareDownload automatically determines whether IPv4 or IPv6 should be used. user Specify a user name for FTP or SSH server access. This operand can be omitted, if the firmware is accessible on a local directory, a USB device, or by anonymous FTP server access. A user name other than "anonymous" is required for SSH server access. pfile Specify a fully qualified path for the firmware pfile. Absolute path names may be specified using forward slashes (/). passwd Specify a password. This operand can be omitted, if the firmware is accessible through a local directory or an attached USB device, or if no password is required by the FTP server. This operand is required when accessing an SSH server. -p scp|ftp Specify the file transfer protocol. Valid values are ftp and scp. The values are not case-sensitive. If -p is not specified, firmwareCommit determines the protocol automatically by checking the config.security parameter. When using the USB option, these parameters, if specified, are ignored. -a fos |sas| any application Specify the type of firmware to be downloaded. Accepted values are fos, sas, or any valid application name. Values are not case-sensitive. -t slot_number(s) Specify the target slots for the firmware download. Valid values are a list of slot numbers separated by comma. -c Disables version compatibility checking. By default, firmwareDownload checks if the firmware being downloaded is compatible with other running firmware images in the system. If the firmware version is not compatible, firmwareDownload fails. If this option is specified, version compatibility checking is disabled. -e Removes all of the installed SA images in the system during SAS firmware download. By default, downloading a SAS image does not remove the installed SA images. If this option is specified, the installed SA images are removed. This option is only valid with the -a sas option. -o Bypasses the checking of Coordinated HotCode Load (HCL). On single CP systems in interop fabrics, the HCL protocol is used to ensure data traffic is not disrupted during firmware upgrades. This option allows firmwareDownload to continue even if HCL is not supported in the fabric or the protocol fails. Using this option may cause traffic disruption for some switches in the fabric. 44 Dell 8/4Gbps FC SAN Module Administrator's Guide 53-1001345-01
