When i check in the console i find device with a "reolad" word .

# multipathd -k"show multipaths  topology"
reload:  base    (3600601602d103300527cc1f06ee6e311) dm-12 DGC,VRAID
[size=900G][features=1 queue_if_no_path][hwhandler=1 emc    ][rw        ]
\_ round-robin 0 [prio=2][enabled]
 \_ 3:0:1:10 sdaq 66:160 [active][ready]
 \_ 2:0:1:10 sdbg 67:160 [active][ready]

Hello Jean-Louis,

The format for multipathd output of devices is:

action_if_any: alias (wwid_if_different_from_alias) dm_device_name_if_known vendor,product size=size features='features' hwhandler='hardware_handler' wp=write_permission_if_known

The reload keyword means that at the time the multipathd command was run, it was reloading the map.

  • You can safely ignore this message if it was a one off.
  • If this is persistent message, please check the hardware.
  • If the hardware is reporting that the device is online and the cabling is good, then you may need to open a support ticket.

Best regards,
Mark
