lsdev shows two identical lines

[CAS_2]

Hi

My HP-UX 11.11 boxes show two lines identical in the output of lsdev command:

# lsdev
Character Block Driver Class
0 -1 cn pseudo
1 -1 asio0 tty
2 -1 SCentIf unknown
3 -1 mm pseudo
4 -1 olar_psm_if olar
5 -1 dev_olar olar
6 -1 devkrs pseudo
7 -1 lpr0 unknown
8 0 sioflop unknown
8 0 sioflop unknown



Is this a bug ?

Hi CAS,

Nope its not a bug but a normal behaviour of the system no need to worry...

Best Regards,

sioflop means super I/O floppy driver which is no longer in use so it is showing as unknown and it is not critical.

I run the lsdev command on my server with same Os but it shows me the following output:
