Hello,
Sorry, it is a bad configuration :
o- qla2xxx ............................................................. [Targets: 1]
o- naa.2100001b3215dd57 ................................................ [gen-acls]
o- acls ............................................................... [ACLs: 1]
| o- naa.2000001b3206f1a1 ...................................... [Mapped LUNs: 1] <-- error
naa.2100001b3206f1a1 is better !!!
The bad performance is due to the Cassini Ethernet Card a Quad 1gb with a pci connector.
The Dell 390 has not pci-x, I found a Brodcom Pcie it is better.
It is better to use fileio with /dev/vgdata/lvdiskfc than a mount disk.
time mkfile 780M toto -> FC 2gb mount lvm
Real : 11.1
user : 0.0
sys : 1.2
time mkfile 780M toto -> FC 2gb /dev/vgdata/lvdiskfc
Real : 4.1
user : 0.0
sys : 1.2
time mkfile 780M toto -> iscsi disk Broadcom pcie 1000e
Real : 6.8
user : 0.0
sys : 1.3
A question :
Is system parameter to control cache like Zil or Arc (see Zfs on linux) ?
Best Regards
Pascal

Objet: Don't see the disk
Hello Andy,
This afternoon, after the iscsi target, I remake the configuration on the server.
I don't touch the precedante configuration on the swicht fiber channel, the card are the same, the initiator is a solarix x86. Same configuration, after the lost of the target's disk.
Before the crash, I have this version : targetcli-2.1.fb34-1.fc20.noarch.rpm, it is hard but I found the missing switch SanBox2 configuration.
But today, I have targetcli.noarch 2.1.fb35-1.fc20 @updates
My qla2xxx is good :
--------------->
/qla2xxx> ls
o- qla2xxx ............................................................. [Targets: 1]

o- luns ............................................................... [LUNs: 1]
o- lun0 ............................ [fileio/bs_fc_test (/dev/vgdata/lvdiskfc)]
---------->
But on the initiator solaris x86 I have :

Specify disk (enter its number): ^C
NO DISK with the fiber channel !!!!
Reboot on Fedora 20, Reboot with configuration on solaris, no effects.
Thank for your help.
Best Regards,
Pascal
