SLES 11SP3 virtual fabric problem on Hyper-V 2012 R2 RRS feed

  • Question

  • Good day every1!

    I do have strong problem with connecting my SUSE Linux Enterprise server 11 SP3 to SAN Disk storage system.

    First of all i do not see my virtual FC adapters inside guest OS. I do see only another devices and do not have any chance to see and change adapters properties:

    sles-hostname:~ #  lspci
    00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (AGP disabled) (rev 03)
    00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 01)
    00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
    00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 02)
    00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual VGA

    Never the less I got WWPNs from VMM console, checked 'em available in the fabric and done the maping to IBM SVC storage.

    The LUN mapped from SAN storage is not recognized properly. I do get fails like this:

    1) i do see some disks with 2 paths instaed of 4. All this paths are pletty strange. Look at this:

    sles-hostname:~ #  ll /dev/sd* | grep -v sda
    brw-rw---- 1 root disk 8, 16 Sep 18 11:20 /dev/sdb
    brw-rw---- 1 root disk 8, 32 Sep 18 11:20 /dev/sdc
    sles-hostname:~ #  ll /dev/disk/by-*/ | egrep -i "sdb|sdc"
    lrwxrwxrwx 1 root root   9 Sep 18 11:20 scsi-360050768019c02417000000000000258 -> ../../sdb
    lrwxrwxrwx 1 root root   9 Sep 18 11:20 wwn-0x60050768019c02417000000000000258 -> ../../sdb
    lrwxrwxrwx 1 root root   9 Sep 18 11:20 vmbus-209ebb94:d858:4341:8719:9194ca09cb76-lun-0 -> ../../sdb
    lrwxrwxrwx 1 root root   9 Sep 18 11:20 vmbus-882f6086:e688:44c2:9f40:4c674f469715-lun-0 -> ../../sdc


    2) And finally the multipath daemon can't recognize them correctly:

    sles-hostname:~ #  multipathd -k
    multipathd> show status
    path checker states:
    up                  2
    
    paths: 2
    busy: False
    multipathd> show paths
    hcil    dev dev_t pri dm_st chk_st dev_st  next_check
    4:0:0:0 sdb 8:16  -1  undef ready  running orphan
    5:0:0:0 sdc 8:32  -1  undef ready  running orphan


    Some lines from messages log:

    sles-hostname:~ #  tail -12 /var/log/messages

    And some more:

    Sep 23 11:28:02 sles-hostname multipathd: sdc: couln't get asymmetric access state


    Plz! Need any help with SLES + Virtual FC on Hyper-V
