Is this a u-dev problem

["hari krishnan" <p.harikrishnan22@xxxxxxxxx>]

Hi all,

 

Is there an issue with Udev, if more than 70 device are connected.

We saw one problem, our SCSI initiator(Linux machine) was connect to SAN box, which was exporting more than 70 LUN's.
but we are not seeing all the LUN's (/dev/sdxx) in initiator side(Linux machine).
However we were able to see appropriate  LUN in sysfs entry.

# ls  /dev/sdjk
ls: /dev/sdjk: No such file or directory
[root@RS_195 pp]# ls  /dev/sdji
ls: /dev/sdji: No such file or directory
[root@RS_195 pp]# ls  /dev/sdjh
ls: /dev/sdjh: No such file or directory
[root@RS_195 pp]# ls  /dev/sdjg
ls: /dev/sdjg: No such file or directory


 [root@RS_195 pp]# ls /block/sdjk
dev     holders  range      size    stat       uevent
device  queue    removable  slaves  subsystem

# /sbin/scsi_id -g -u -s /block/sdjk
2000b080181002158

I manually created /dev/sdjk by using command mknod, it worked.

 

I don't have log as of now, I have enabled the log for udev in udev.conf file.
Could you please tell me, it this a know problem in udev.

I appreciate your help.

Thanks,
Hari
