set iscsi-parameters


Description	Changes system-wide parameters for iSCSI host ports in each controller module. CAUTION:Applying new parameters to the ports or modifying unused ports may cause hosts to lose access to the storage system.
Minimum role	manage
Syntax	set iscsi-parameters [chap enabled\|disabled\|on\|off] [iscsi-ip-version ipv4\|ipv6] [isns enabled\|disabled\|on\|off] [isns-alt-ip `iSNS-IP`] [isns-ip `iSNS-IP`] [jumbo-frame enabled\|disabled\|on\|off] [speed auto\|1gbps]
Parameters	[chap enabled\|disabled\|on\|off] Optional. Enables or disables use of Challenge Handshake Authentication Protocol. Disabled by default. When CHAP is enabled and the storage system is the recipient of a login request from a known originator (initiator), the system will request a known secret. If the originator supplies the secret, the connection will be allowed [iscsi-ip-version ipv4\|ipv6] Optional. Specifies whether to use IP version 4 (IPv4) or 6 (IPv6) for addressing controller iSCSI ports. ipv4: Lets you specify addresses in dot-decimal format, where the four octets of the address use decimal values without leading zeroes and the octets are separated by a period. For example, 10.132.2.205. This option is the default. ipv6: Lets you specify addresses using eight groups of four hexadecimal digits, where the groups are separated by a colon. All groups must be specified. For example, 0000:0000:0000:0000:0000:0000:0A90:3442. [isns enabled\|disabled\|on\|off] Optional. Enables or disables registration with a specified Internet Storage Name Service server, which provides name-to-IP-address mapping. Disabled by default. [isns-alt-ip `iSNS-IP`] Optional. Specifies the IP address of an alternate iSNS server, which can be on a different subnet. The default address is all zeroes. [isns-ip `iSNS-IP`] Optional. Specifies the IP address of an iSNS server. The default address is all zeroes. [jumbo-frame enabled\|disabled\|on\|off] Optional. Enables or disables support for jumbo frames. Allowing for 100 bytes of overhead, a normal frame can contain a 1400-byte payload whereas a jumbo frame can contain a maximum 8900-byte payload for larger data transfers. Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network components in the data path. Disabled by default [speed auto\|1gbps] Sets the host port link speed. auto: Auto-negotiates the proper speed. This is the default. 1gbs: Forces the speed to 1 Gbit/s, overriding a downshift that can occur during auto-negotiation with 1-Gbit/s HBAs. This setting does not apply to 10-Gbit/s HBAs.
Examples	For a storage system using IPv4 addressing whose host ports are connected to different subnets, enable CHAP, specify the IP address of the iSNS server on each subnet, and enable registration with either server. # set iscsi-parameters chap enabled isns enabled isns-ip 10.10.10.93 isns-alt-ip 10.11.10.90 Specify that iSCSI ports will use IPv6 addressing. # set iscsi-parameters iscsi-ip-version ipv6
