Remove old subpaths from vxvm/format/cfgadm
Hi, I`m having a server, that was initially having 2 HBA`s, and dmpnodes were creates with 2 subpaths:
Code:
# vxdisk -o alldgs list
DEVICE       TYPE            DISK         GROUP        STATUS
c0t0d0s2     auto:none       -            -            online invalid
c0t1d0s2     auto:none       -            -            online invalid
c0t2d0s2     auto:none       -            -            online invalid
c0t3d0s2     auto:none       -            -            online invalid
c2t5006048452A724A7d37s2 auto:cdsdisk    emc1         B08  online
c2t5006048452A724A7d38s2 auto:cdsdisk    emc2         V01  online
c2t5006048452A724A7d39s2 auto:cdsdisk    emc02F2      D43  online
....

one HBA died/offlined
Code:
bash-3.00# luxadm -e port
/devices/pci@7c0/pci@0/pci@1/pci@0,2/SUNW,qlc@1/fp@0,0:devctl      CONNECTED

I still have those dead subpaths in format/cfgadm

Question is - how can I get rid of dead subpaths in vxdmpadm output and how to get rid of them in cfgadm/format output?

What I already tried:
Code:
luxadm -e offline /dev/rdsk/c4t5006048452A72498d106
cfgadm -c unconfigure c4::dsk/5006048452a72498,106
luxadm -e forcelip /dev/cfg/c4
devfsadm -Cv
cfgadm -c unconfigure -o unusable_SCSI_LUN c4::5006048452a72498,106

No joy.

Anyone?

once check the disk controller if they are enable then go for the diskunsetup and setup then after try for vxdisk scandisks after that its not an real time sugestable command it restarts the daemon(vxconfigd -k)

Old 04-16-2011
Two things you need to do

1. copy the /etc/vx/vxdmpexclude to as vxdmpexclude.old and /etc/vx/vxvmexclude as vxvmexclude.old
2.Go to vxdiskadm menu and choose option 17 (i believe)

then run vxconfigd -k

Old 04-18-2011
Hmm, this is a prod system, so I`m not very sure I can run mentioned commands without minor outages.

Is restarting of vxconfigd safe? Also, restarting of it will remove devnodes from /dev ?

Old 04-18-2011
masloff,

Does it hosts any clusters or only the VxVM
# 6  
Old 04-26-2011
Yes, this host is a part of VCS; anyway, we decided not to spend too much time on this one, and wait for opportunity to restart.

Thanks anyone!
