Add the following lines at the end of the "devices" section.

(This example is for the ETERNUS DX410)

devices {

device {

vendor "FUJITSU"

product "ETERNUS_DX400"

prio alua

path_grouping_policy group_by_prio

path_selector "round-robin 0"

failback immediate

no_path_retry 0 (*1)

path_checker tur

dev_loss_tmo 2147483

fast_io_fail_tmo 1

}

*1: When using the Storage Cluster function, specify "no_path_retry 10".

• Enter a space between "defaults" and "{".

• Enter a space between "devices" and "{".

• Enter a space between "device" and "{".

• The "dev_loss_tmo" parameter value is not applied correctly when a Brocade Fibre Channel card is

used. This may cause the device file to be cleared if the

ETERNUS DX is turned off due to a power

failure. If this occurs, the server may have to be rebooted.

The "product" value varies depending on the ETERNUS DX that is to be connected.

Refer to the following table for the appropriate value.

ETERNUS DX to be used "product" value

DX60 S3/DX100 S3/DX200 S3,

DX200F,

DX60/DX60 S2, DX80/DX80 S2, DX90/DX90 S2

ETERNUS_DXL

DX500 S3/DX600 S3 ETERNUS_DXM

DX400/DX400 S2 series ETERNUS_DX400

DX8000/DX8000 S2 series ETERNUS_DX8000

If any internal disks or other devices are to be excluded from the multipath configuration, specify the
