AIX is connected to IBM storage. Common commands for multi-path software: view the storage disk Path 1. view the storage disk path of MPIO # lspath (applicable to MPIO path queries for all storage) # mpio_get_config-Av (applicable to the MPIO path query of DS3K/DS4K) 2. view the path of the RDAC storage disk # fget_config-Av (applicable to the RDAC path query of DS3K/DS4K) 3. view the path of the SDDPCM storage disk # pcmpath query device (SDDPCM path query for DS6K/DS8K and v7000) # pcmpath query adapter check SDDPCM adapter status # pcmpath query wwpn check SDDPCM known FC adapter WWPN # pcmpath query version check SDDPCM level # lspath check whether all disk paths are enabled 4. view the current operation multi-path software that supports IBM storage # manage_disk_drivers 5. Change the default multi-path software of DS4700 to RDAC # manage_disk_drivers-d DS4700-o AIX_fcparray
