Respondiendo al comentario de gonzo34 a ese post solicitando mas informacion sobre como usar iSCSI en Solaris, voy a poner aqui mis notas sobre el tema.
En el linux, que “exporta” por iSCSI el disco (o el lvol), instalamos el iSCSI Target. Una vez instalado, indicamos al demonio qué disco/lvol exportar (por ejemplo el /dev/vg01/lviscsi01):
# vi /etc/ietd.conf #IncomingUser nwsmith secretsecret Target iqn.2006-06.com.alegrome:storage.lvm Lun 0 /dev/vg01/lviscsi01 Alias iscsitest01
Iniciamos el demonio (o lo reiniciamos):
# service iscsi-target start Starting iSCSI target service: [ OK ]
Comprobamos que este arriba el demonio:
# netstat -ntlp | grep 3260
tcp 0 0 0.0.0.0:3260 0.0.0.0:* LISTEN 3160/ietd
# tail /var/log/messages

Ahora en la solaris (cambiar IP por la IP del Linux):
# iscsiadm add discovery-address IP:3260
# iscsiadm modify discovery --sendtargets enable
# iscsiadm list discovery
Discovery:
Static: disabled
Send Targets: enabled
iSNS: disabled
# devfsadm -v -i iscsi
devfsadm[752]: verbose: symlink /dev/dsk/c1t2d0s0 -> ../../devices/iscsi/disk@0000iqn.2006-06.com.alegrome%3Astorage.lvm0001,0:a
[...]
Ya vemos el disco con el format:
# format

Vemos los targets descubiertos:
# iscsiadm list target

Por otra parte en la Linux, vemos la session iSCSI:
alegrome# cat /proc/net/iet/session

sid:281475681353792 initiator:iqn.1986-03.com.sun:01:0800209efab9.46bc3c8b

Espero que le sirva a alguien ;-)
