The commands that are shown in Example 7-9 and Example 7-10 determine whether the IBM  Spectrum Virtualize is properly connected. They show at a glance which ASL is used (native  DMP ASL or SDD ASL). Example 7-9 shows what you see when Symantec Volume Manager correctly accesses IBM  Spectrum Virtualize by using the SDD pass-through mode ASL. Example 7-10 shows what you see when IBM Spectrum Virtualize is configured by using  native DMP ASL. For the latest ASL levels to use native DMP, see the array-specific module table at this  website: https://sort.symantec.com/asl For the latest Veritas Patch levels, see the patch table at this website: https://sort.symantec.com/patch/matrix To check the installed Symantec Veritas version, enter the following command: showrev -p |grep vxvm To check which IBM ASLs are configured into the Volume Manager, enter the following  command: vxddladm listsupport |grep -i ibm After you install a new ASL by using the  pkgadd  command, restart your system or run the  vxdctl enable  command. To list the ASLs that are active, enter the following command: vxddladm listsupport To determine the various VMware ESXi levels that are supported, see the IBM System  Storage Interoperation Center (SSIC) available at:  IBM SSIC 7.11 VMware server 7.10.3 DMP multipathing Example 7-9 Symantec Volume Manager using SDD pass-through mode ASL Example 7-10 IBM Spectrum Virtualize that is configured by using native ASL # vxdmpadm list enclosure all ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS ============================================================ OTHER_DISKS OTHER_DISKS OTHER_DISKS CONNECTED VPATH_SANVC0 VPATH_SANVC 0200628002faXX00 CONNECTED # vxdmpadm listenclosure all ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS ============================================================ OTHER_DISKS OTHER_DSKSI OTHER_DISKS CONNECTED SAN_VC0 SAN_VC 0200628002faXX00 CONNECTED 264  IBM FlashSystem 9200 and 9100 Best Practices and Performance Guidelines
