missing disks and reboot wont solve it
I am very new to veritas. We have AIX 7.1 server using veritas DMP. When I look at the VIO all of the virtual fibre channel adapters are logged in, but on the lpar it is failing to see any disks on fscsi0 and fscsi1. I have been going back and forth with IBM and symantec and cannot get this resolved, so decided to pick your brains here. # lsdev| grep fscsi fscsi0 Available 01-T1-01 FC SCSI I/O Controller Protocol Device fscsi1 Available 02-T1-01 FC SCSI I/O Controller Protocol Device fscsi2 Available 03-T1-01 FC SCSI I/O Controller Protocol Device fscsi3 Available 04-T1-01 FC SCSI I/O Controller Protocol Device fscsi4 Available 05-T1-01 FC SCSI I/O Controller Protocol Device fscsi5 Available 06-T1-01 FC SCSI I/O Controller Protocol Device fscsi6 Available 07-T1-01 FC SCSI I/O Controller Protocol Device fscsi7 Available 08-T1-01 FC SCSI I/O Controller Protocol Device # vxdmpadm listctlr CTLR_NAME ENCLR_TYPE STATE ENCLR_NAME PATH_COUNT ========================================================================= fscsi2 Hitachi_VSP ENABLED hitachi_vsp0 44 fscsi3 Hitachi_VSP ENABLED hitachi_vsp0 44 fscsi4 Hitachi_VSP ENABLED hitachi_vsp0 44 fscsi5 Hitachi_VSP ENABLED hitachi_vsp0 44 fscsi6 Hitachi_VSP ENABLED hitachi_vsp0 44 fscsi7 Hitachi_VSP ENABLED hitachi_vsp0 44 ^ Above you will see that fscsiX seen by OS is not being seen by veritas. How can I force them into veritas? I have already tried rebooting the VIO and LPAR and that doesnt seem to help. FWIW, i deleted the disks that were in defined state. Usually when MPIO is being used and we lose path, deleting the disks and virtual fibrechannel adapter and running cfgmgr solves the issue, but that doesnt seem to help here.Solved
SFHACFS vs Hitachi-VSP & Host mode option 22
Hi! I'm installing several new SFHACFS clusters and during the failover testing I run into annoying problem - when I fence one node of the cluster, DMP logs high number of path down/path up events which in the end causes the disk to disconnect even on other active nodes. We've found out that our disks were exported without the host mode option 22, so we fixed this on storage. Even after this the clusters bahaved the same. Later I've read somewhere on internet, that it's good idea to relabel the disks, so I've requested new disks from storage and did vxevac to new disks. This fixed just two clusters we have, but the other two are behaving still the same. Have anybody experienced anything similar? Do you know anything I can test / check on the servers to determine the difference? The only difference between the enviroment is that the not-working clusters have the disks mirrored from two storage systems, while the working ones have the data disks only from one storage.Solved
Dynamic multipath using EMC storage Veritas 3.5
I am trying to setup multipathing with EMC Clariion. The problem is that vxdisk list fabric_0 only shows one path. The EMC array is in auto-trespass mode. This is solaris 8 and format shows two paths. # vxdisk list fabric_2 Device: fabric_2 devicetag: fabric_2 type: sliced hostid: ncsun1 disk: name=disk05 id=1302111549.6037.ncsun1 group: name=rootdg id=1072877341.1025.nc1 info: privoffset=1 flags: online ready private autoconfig autoimport imported pubpaths: block=/dev/vx/dmp/fabric_2s4 char=/dev/vx/rdmp/fabric_2s4 privpaths: block=/dev/vx/dmp/fabric_2s3 char=/dev/vx/rdmp/fabric_2s3 version: 2.2 iosize: min=512 (bytes) max=2048 (blocks) public: slice=4 offset=0 len=1048494080 private: slice=3 offset=1 len=32511 update: time=1302111558 seqno=0.5 headers: 0 248 configs: count=1 len=23969 logs: count=1 len=3631 Defined regions: config priv 000017-000247[000231]: copy=01 offset=000000 enabled config priv 000249-023986[023738]: copy=01 offset=000231 enabled log priv 023987-027617[003631]: copy=01 offset=000000 enabled Multipathing information: numpaths: 1 c10t500601613B241045d5s2 state=enabled formt 8. c10t500601613B241045d0 <DGC-RAID5-0428 cyl 63998 alt 2 hd 256 sec 64> /ssm@0,0/pci@19,700000/SUNW,qlc@2/fp@0,0/ssd@w500601613b241045,0 16. c16t500601603B241045d0 <DGC-RAID5-0428 cyl 63998 alt 2 hd 256 sec 64> /ssm@0,0/pci@18,700000/SUNW,qlc@1/fp@0,0/ssd@w500601603b241045,0 vxdisk -o alldgs list show both paths. Two things here it should only show one of the paths and also the second path it shows with diskgroup in ( ). Another issue is why the disk dont show up as EMC_0 or similiar. *****The server has T3 connect and EMC which we are migrating from T3 to EMC.
