DDL provides an interface to set and display certain parameters that affect the performance of the iSCSI device path. However, the underlying OS framework must support the ability to set these values. The vxddladm set command returns an error if the OS support is not available.
Table: Parameters for iSCSI devices
To get the iSCSI operational parameters on the initiator for a specific iSCSI target
# vxddladm getiscsi target=tgt-id {all | parameter}
You can use this command to obtain all the iSCSI operational parameters.
# vxddladm getiscsi target=c2_p2_t0
