    Default iscsi and Solaris slow to reboot

    I have setup ISCSI on my Solaris 10x86 system and all works fine, but when I reboot my system it takes for ever to shutdown. Is any one else getting this. See below for example:

    # svcadm enable iscsi/initiator
    # iscsiadm add static-config iqn.2010-03.uk.ac.bbk.dcs:bran0.cronus0,192.x.x.x
    # modify discovery --static enable
    # iscsiadm list discovery
    Discovery:
    Static: enabled
    Send Targets: disabled
    iSNS: disabled

    # iscsiadm list initiator-node
    Initiator node name: iqn.1986-03.com.sun:01:2a3566efffff.4b8cf988
    Initiator node alias: cronus
    Login Parameters (Default/Configured):
    Header Digest: NONE/-
    Data Digest: NONE/-
    Authentication Type: NONE
    RADIUS Server: NONE
    RADIUS access: unknown
    Configured Sessions: 1

    # format < /dev/null
    AVAILABLE DISK SELECTIONS:
    2. c2t3d0 <SCST_BIO-jGhxX2TSzK2Sv8jl- 101-500.00GB>
    /iscsi/disk@0000iqn.2010-03.uk.ac.bbk.dcs%3Abran0.cronus0FFFF,0
    3. c2t4d0 <SCST_BIO-111M2sds3BP2LurB- 101-50.00GB>
    /iscsi/disk@0000iqn.2010-03.uk.ac.bbk.dcs%3Abran0.cronus0FFFF,1
    Specify disk (enter its number):

    Now If I do a reboot all is fine, but when I mount a disk and start a reboot, it takes about 15minutes to shutdown:

    # mount /dev/dsk/c2t4d0s0 /a
    # init 6
    Mar 8 11:29:25 cronus iscsi: [ID 213721 kern.notice] NOTICE: iscsi session(4) - session logout failed (20)
    Mar 8 11:29:25 cronus iscsi: [ID 537996 kern.notice] NOTICE: iscsi discovery failure - SendTargets method is not enabled
    Mar 8 11:29:25 cronus iscsi: [ID 299153 kern.notice] NOTICE: iscsi discovery failure - iSNS method is not enabled
    Mar 8 11:39:26 cronus svc.startd[7]: [ID 122153 daemon.warning] svc:/network/iscsi/initiator:default: Method or service exit timed out. Killing contract 35.
    Mar 8 11:39:26 cronus svc.startd[7]: [ID 748625 daemon.error] network/iscsi/initiator:default failed: transitioned to maintenance (see 'svcs -xv' for details)

    As you can see time passes very slowly.....

    Any pointers..
