  • 1.  IBM DS3500 and ALUA

    Hi All,

    We have a client who has a new IBM DS3512 (1746) SAN, we're connecting via iSCSI with vSphere 5.0 U1.  The firmware on the DS3512 is 07.84.44.00.

    According to this article and IBM's announcment, ESXi 5 should use the VMW_SATP_ALUA SATP with this storage device, but I have checked via esxcli and it is set as VMW_SATP_LSI.

    I don't understand what is going on.  Can anybody tell me how I get this working correctly, or why it's set this way?

    Did you change the host type in the san configuration?

    Thanks for replying Rebelinux.

    The Host is set to host type of VMWARE in the IBM DS Storage Manager.

    I have discovered in the IBM Release Notes for the DS Storage Manager,  there is a seperate host type of VMwareTPGSALUA that must be selected.  I  will make this change, test, and update this discussion with the  results.  Thanks to Rebelinux for the prompt in the right direction.

    After changing the Host Type in the IBM DS SM from VMWARE to VMwareTPGSALUA, Restarting the ESX host & Rescanning HBAs, the issue is now resolved.

    Thanks again to Rebelinux. :smileygrin:

    Hello,

    which multipathing policy are you using with IBM 3524, ALUA, VMWARE 5i U1 ?

    thanks

    I have an IBM DS3500 ISCSI 1GB/s with 7.84.44.00 firmware, connected to two ESX version is 4.1U3 path11 buil 988178

    Do you know about compatibility of multipathing ALUA with ESX 4.1U3?

    Look this link:http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14900863&tstart=0

    an ALUA-supported multipath driver is installed in the host

    How can I check if my ESX host there is an ALUA-supported multipath driver?

    All currently supported versions of ESXi support ALUA.

    As mentioned, ALUA is supported on all current ESXi versions.

    You can check the current runtime status of LUNs and whether they are being accessed with ALUA by checking if the VMW_SATP_ALUA SATP claimed the storage device.

    You can do so via the GUI or more verbose from the ESXi shell like this:

    # esxcli storage nmp device list
    naa.600508b40010439a0000b000003b0000
       Device Display Name: HP Fibre Channel Disk (naa.600508b40010439a0000b000003b0000)
       Storage Array Type: VMW_SATP_ALUA
       Storage Array Type Device Config: {implicit_support=on;explicit_support=on; explicit_allow=on;alua_followover=on;{TPG_id=1,TPG_state=ANO}{TPG_id=2,TPG_state=AO}}
       Path Selection Policy: VMW_PSP_MRU
       Path Selection Policy Device Config: Current Path=vmhba2:C0:T1:L2
       Path Selection Policy Device Custom Config:
       Working Paths: vmhba2:C0:T1:L2
       Is Local SAS Device: false
       Is Boot USB Device: false

    Sorry for the bump, but I just found myself in the same situation.

    We have this in production with 4 hosts going through a LSI sas switch. Is it possible to change this on the DS3500, reboot the hosts without adverse effects?

    To confirm, I have the host operating system set to VMWARE instead of the other VMWARE one... so I have LSI showing up as the driver.
