cldev populate and devfsadm doesn't work

Hello,

We have 2 x M4000 cluster nodes, connected to 2540 storage.

When I issue the command cldev populate -v or devfsadm it doesn't work knowing that all disks are accessible and working properly, when I traced the processes they are stuck accessing a disk,

here is my troubleshooting:

root# ps -ef|grep cldev

    root 26691 26417   0 10:04:49 pts/2       0:00 cldev populate -v

 

root# truss -Elfp 26691

26691/1:        waitid(P_PID, 26692, 0xFFBFF630, WEXITED|WTRAPPED) (sleeping...)

root# truss -Elfp 26692

26692/1:        waitid(P_PID, 26718, 0xFFBFE770, WEXITED|WTRAPPED) (sleeping...)

root# truss -Elfp 26718

26718/1:        waitid(P_PID, 26719, 0xFFBFF590, WEXITED|WTRAPPED|WNOWAIT) (sleeping...)

root# truss -Elfp 26719

26719/1:        read(3, 0xFFBFF3E0, 1)          (sleeping...)

root# ps -ef|grep 26719
