hpux-1131与EMC-cx500的配置.docx

参照EMC Host Connectivity Guide for HP-UX正确的设定应该是：initiator type必须设定为HP No Auto Trespass (存储端)failover mode 必须设定为4(ALUA). （存储端）FLARE-Operating-Environment必须是支持HP-UX 11.31. （存储端-版本）hpux1131与EMCcx500的配置(2012-01-09 22:35:50)转载标签：it分类：hp-uxIm currently benchmarking a RX6600.30mins - yes - there is definately something very wrong there.Now mine isnt on a clariion - its on a DMX1000 and DMX3From the output below, frame 65 is the 1000 and 52 is the DMX3.# prealloc /tmp/bigfile 409600000# timex cp /tmp/bigfile /v01/real 11.95user 0.00sys 0.18mkdir /dev/vg11mknod /dev/vg11/group c 64 0x0b0000vgcreate -s 32 -p 64 -e 32768 /dev/vg11 /dev/disk/disk23 /dev/disk/disk24 /dev/disk/disk25# ioscan -m dsfPersistent DSF Legacy DSF(s)=/dev/pt/pt1 /dev/rscsi/c1t0d0/dev/pt/pt3 /dev/rscsi/c3t0d0/dev/rdisk/disk4 /dev/rdsk/c0t1d0/dev/rdisk/disk4_p3 /dev/rdsk/c0t1d0s3/dev/rdisk/disk4_p1 /dev/rdsk/c0t1d0s1/dev/rdisk/disk4_p2 /dev/rdsk/c0t1d0s2/dev/pt/pt5 /dev/rscsi/c5t0d0/dev/rdisk/disk5 /dev/rdsk/c0t0d0/dev/rdisk/disk5_p1 /dev/rdsk/c0t0d0s1/dev/rdisk/disk5_p2 /dev/rdsk/c0t0d0s2/dev/rdisk/disk5_p3 /dev/rdsk/c0t0d0s3/dev/pt/pt7 /dev/rscsi/c7t0d0/dev/rdisk/disk7 /dev/rdsk/c2t0d0/dev/rdisk/disk9 /dev/rdsk/c4t0d0/dev/rdisk/disk18 /dev/rdsk/c4t9d0/dev/rdisk/disk19 /dev/rdsk/c4t9d1/dev/rdisk/disk20 /dev/rdsk/c4t9d2/dev/rdisk/disk21 /dev/rdsk/c4t9d3/dev/rdisk/disk22 /dev/rdsk/c2t9d0/dev/rdisk/disk23 /dev/rdsk/c2t9d1/dev/rdisk/disk24 /dev/rdsk/c2t9d2/dev/rdisk/disk25 /dev/rdsk/c2t9d3/dev/rdisk/disk27 /dev/rdsk/c6t0d0/dev/rdisk/disk29 /dev/rdsk/c8t0d0/dev/rdisk/disk38 /dev/rdsk/c8t4d0/dev/rdisk/disk39 /dev/rdsk/c8t4d2/dev/rdisk/disk40 /dev/rdsk/c8t3d7/dev/rdisk/disk41 /dev/rdsk/c8t4d1/dev/rdisk/disk42 /dev/rdsk/c6t4d0/dev/rdisk/disk43 /dev/rdsk/c6t3d7/dev/rdisk/disk44 /dev/rdsk/c6t4d1/dev/rdisk/disk45 /dev/rdsk/c6t4d2# inqInquiry utility, Version V7.3-771 (Rev 0.0) (SIL Version V (Edit Level 771)Copyright (C) byEMCCorporation, all rights reserved.For help type inq -h.-DEVICE :VEND :PROD :REV :SER NUM :CAP(kb)-/dev/rdsk/c0t0d0 :HP :DG072ABAB3 :HPD5 :3NP0D3VQ : 71687369/dev/rdsk/c0t0d0s1 :HP :DG072ABAB3 :HPD5 :3NP0D3VQ : 71687369/dev/rdsk/c0t0d0s2 :HP :DG072ABAB3 :HPD5 :3NP0D3VQ : 71687369/dev/rdsk/c0t0d0s3 :HP :DG072ABAB3 :HPD5 :3NP0D3VQ : 71687369/dev/rdsk/c0t1d0 :HP :DG072ABAB3 :HPD5 :3NP0BTRC : 71687369/dev/rdsk/c0t1d0s1 :HP :DG072ABAB3 :HPD5 :3NP0BTRC : 71687369/dev/rdsk/c0t1d0s2 :HP :DG072ABAB3 :HPD5 :3NP0BTRC : 71687369/dev/rdsk/c0t1d0s3 :HP :DG072ABAB3 :HPD5 :3NP0BTRC : 71687369/dev/rdsk/c2t9d0 :EMC:SYMMETRIX :5670 :6500780000 : 35354880/dev/rdsk/c2t9d1 :EMC:SYMMETRIX :5670 :650079c000 : 35354880/dev/rdsk/c2t9d2 :EMC:SYMMETRIX :5670 :6500774000 : 35354880/dev/rdsk/c2t9d3 :EMC:SYMMETRIX :5670 :650077c000 : 35354880/dev/rdsk/c4t9d0 :EMC:SYMMETRIX :5670 :6500780000 : 35354880/dev/rdsk/c4t9d1 :EMC:SYMMETRIX :5670 :650079c000 : 35354880/dev/rdsk/c4t9d2 :EMC:SYMMETRIX :5670 :6500774000 : 35354880/dev/rdsk/c4t9d3 :EMC:SYMMETRIX :5670 :650077c000 : 35354880/dev/rdsk/c6t0d0 :EMC:SYMMETRIX :5771 :5200022000 : 5760/dev/rdsk/c6t3d7 :EMC:SYMMETRIX :5771 :52000e3000 : 77760000/dev/rdsk/c6t4d0 :EMC:SYMMETRIX :5771 :52000e7000 : 77760000/dev/rdsk/c6t4d1 :EMC:SYMMETRIX :5771 :52000eb000 : 77760000/dev/rdsk/c6t4d2 :EMC:SYMMETRIX :5771 :52000ef000 : 77760000/dev/rdsk/c8t0d0 :EMC:SYMMETRIX :5771 :5200022000 : 5760/dev/rdsk/c8t3d7 :EMC:SYMMETRIX :5771 :52000e3000 : 77760000/dev/rdsk/c8t4d0 :EMC:SYMMETRIX :5771 :52000e7000 : 77760000/dev/rdsk/c8t4d1 :EMC:SYMMETRIX :5771 :52000eb000 : 77760000/dev/rdsk/c8t4d2 :EMC:SYMMETRIX :5771 :52000ef000 : 77760000# vgdisplay -v vg11- Volume groups -VG Name /dev/vg11VG Write Access read/writeVG Status availableMax LV 255Cur LV 1Open LV 1Max PV 64Cur PV 3Act PV 3Max PE per PV 32768VGDA 6PE Size (Mbytes) 32Total PE 3234Alloc PE 3234Free PE 0Total PVG 0Total Spare PVs 0Total Spare PVs in use 0- Logical volumes -LV Name /dev/vg11/lvdata01LV Status available/syncdLV Size (Mbytes) 103488Current LE 3234Allocated PE 3234Used PV 3- Physical volumes -PV Name /dev/disk/disk23PV Status availableTotal PE 1078Free PE 0Autoswitch OnPV Name /dev/disk/disk24PV Status availableTotal PE 1078Free PE 0Autoswitch OnPV Name /dev/disk/disk25PV Status availableTotal PE 1078Free PE 0Autoswitch OnWere just checking the Clariion initiator setting. for DMP if I have understood correctly it seems that it should be No Auto-Trespass + Failover Mode=2.11iv3 native multipathing supports active-active arrays transparently without needing any vendor supplied plug-ins.Active-passive arrays need to either support ALUA (See Section 5.8 of/ftp/t10/drafts/spc3/spc3r23.pdf)or the active-passive array vendor needs to supply an apsw plug-in for their array. See :/portal/download/files/unprot/ddk/APSWWPAPER.pdfOkay everone, here goes with our home-brewed, unsupported configuration. which works for now.Config for Clariion-side CX700:- We must first configure the two 2 initiators for our server in the following way on the Clariion:=Initiator Type: HP No Auto TrespassFailover Mode: 2=Config for Server-side (HP-UX 11.31):-In our current configuration, we have 2 HBAs: the first is hooked up to SP-A on the Clariion and the second, SP-B. As already established, its not possible to perform load-balancing, because the Clariion CX700 fonctions in Active/Passive mode. Therefore we have to change the load-balancing policy for each LUN in order to replicate a basic failover mode (hot spare if you like).To do that we need to use the preferred_path argument for scsimgr.First though we need the hardware adress in hex. ugh!To get that we run ioscan with the following args.=# ioscan -fnNkCdiskClass I H/W Path Driver S/W State H/W Type Description=disk 13 64000/0xfa00/0x1 esdisk CLAIMED DEVICE DGC CX700WDR5/dev/disk/disk13 /dev/rdisk/disk13disk 14 64000/0xfa00/0x2 esdisk CLAIMED DEVICE DGC CX700WDR5/dev/disk/disk14 /dev/rdisk/disk14disk 15 64000/0xfa00/0x3 esdisk CLAIMED DEVICE DGC CX700WDR5/dev/disk/disk15 /dev/rdisk/disk15disk 16 64000/0xfa00/0x4 esdisk CLAIMED DEVICE DGC CX700WDR5/dev/disk/disk16 /dev/rdisk/disk16disk 20 64000/0xfa00/0x8 esdisk CLAIMED DEVICE HP 146 GMAT3147NC/dev/disk/disk20 /dev/rdisk/disk20disk 21 64000/0xfa00/0x9 esdisk CLAIMED DEVICE TEAC DV-28E-N/dev/disk/disk21 /dev/rdisk/disk21disk 26 64000/0xfa00/0xc esdisk CLAIMED DEVICE HP 146 GMAT3147NC/dev/disk/disk26 /dev/rdisk/disk26disk 24 64000/0xfa00/0xd esdisk CLAIMED DEVICE DGC CX700WDR5/dev/disk/disk24 /dev/rdisk/disk24=Then we fix the so called load-balancing policy.=/usr/sbin/scsimgr save_attr -H 64000/0xfa00/0xd -a load_bal_policy=preferred_path=To find out the exact hardware path to fix as preferred you need to use the following command.=# /usr/sbin/scsimgr lun_map -D /dev/rdisk/disk24LUN PATH INFORMATION FOR LUN : /dev/rdisk/disk24Total number of LUN paths = 2World Wide Identifier(WWID) = 0x60060160ce0b1600a242ce17f917dc11LUN path : lunpath16Class = lunpathInstance = 16Hardware path = 0/3/1/0/4/0.0x5006016930600f94.0x4007000000000000SCSI transport protocol = fibre_channelState = ACTIVELast Open or Close state = ACTIVELUN path : lunpath15Class = lunpathInstance = 15Hardware path = 0/4/1/0/4/0.0x5006016130600f94.0x4007000000000000SCSI transport protocol = fibre_channelState = ACTIVELast Open or Close state = ACTIVE=After activating that policy we now force the path for the LUN to be point to the corresponding SP on the Clariion.

CLARiiON arrays are active/passive. We already support native MPIO for Sun and Windows. For HP/UX, we cant promise anything since the ball is mostly in HPs court. We hope so but looks like it will be a patch to 11iv3 to enable it.along with release 26 on the CLARiiON.Lastly, let me say this. Ive been told if you move ahead (ie above) on anything other than R26, you will have data corruption issues. EMCrep is only partially correct.HP-UX 11.31 does support active/passive as well as asymmetric active-active arrays. However, it requires the array vendor to support ALUA or to provide the apsw plug-in. ALUA is already supported by a number of the well known mid-range as
