Each time I am rebooting the HP UX machine, the mount for all other machines are lost.
Is there any possible to ensure it would not happend?
If so, how?
Thanks,
Yaron

Re: auto mount
have not you mentioned them in /etc/fstab ,
(expect when FS is in cluster)
what tye of application you have on servers..how does this application utilizes the underlying disk structure , please provide more details.A fstab should look like this :
~
/dev/vg01/mango08 /mango08 vxfs defaults 0 2
/dev/vg01/mango09 /mango09 vxfs defaults 0 2
/dev/vg01/mango10 /mango10 vxfs defaults 0 2
/dev/vg01/mango11 /mango11 vxfs defaults 0 2
/dev/vg01/mango12 /mango12 vxfs defaults 0 2
/dev/vg01/mango13 /mango13 vxfs defaults 0 2
/dev/vg01/mango14 /mango14 vxfs defaults 0 2

Re: auto mount
i misread the thread "the mount for all other machines are lost"....i guess you are having NFS export form the server and having the NFS client to mount the same .

Re: auto mount
No, I didn't mention it.
Indeed, it is NFS and I dont quite sure who is the server and who is the client (I read that it could be both).
Now I looked on other HP machin on the fstab file and I have seen your meaning. Let me be more familiar with the line from it:
ednop:/vol/vol0/scc /ednop nfs rw,suid,soft,bg 0 0
Please let me know what are the following refer to:
ednop:/vol/vol0/scc /ednop nfs rw,suid,soft,bg 0 0
for example:
ednop - machine name (i know)
vol,vol0,scc (i know)
rw?
suid?
soft?
bg?
0,0?
should I define it by myself? what are the defenitions options I have?
regards.

Re: auto mount
First check if your NFS server is permanently sharing the filesystem in /etc/dfs/dfstab on 11.31 and /etc/exports on 11.23 and check on the client side if the nfs entry is there for mounting permanently on /etc/fstab. This is an approach to your problem.
OK, so what i understand from your query is what are mount options . Now these are some options for mount...
ro/rw :- exapansion read only/read write
suid/nosuid :- Do u want suid bit set??
quota/noquota :- Do u want a filesystem quota set?
The 0 0 refers to backup frequency and fsck order. Backup frequency is like a "dummy" field in modern HPUX operating systems but you still need a placeholder 0 over there.
soft on NFS would refer to a soft mount. You will also see options on NFS mounts that deal with the behaviour of the NFS substystem when the NFS server hangs. Don't forget to assign appropriate points. :)

You better know this.
>ednop:/vol/vol0/scc /ednop nfs rw,suid,soft,bg 0 0
You are mounting it R/W, you allow SUID programs. Your retry is soft.
See mount_nfs(1M):

Re: auto mount
Just adding to Mr. Dennis Handly's comments. Since your topic is "auto mount", if you remove that space the terminology typically relates to AutoFS. But I don't think you (Yarok) are talking about direct, special or indirect maps. In case you are, the NFS client side service involves one essential file called as AUTOFS master map. You don't mention it in /etc/fstab, it automatically mounts and unmounts depending on access and idle time respectively.

Re: auto mount
Sorry for the dalay with assigning points and answer.
The OS does not have the file /etc/dfs/dfstab
I dont know what is 11.31 and 11.23.
Do you prefer that I will attach the files: /etc/dfstab /etc/mnttab and /etc/exports.?
Please advice.

Re: auto mount
It isn't likely to be there on 11.23, just a dummy one.
>I don't know what is 11.31 and 11.23.
This is scary, 11i v2 and 11i v3. Look at: uname -a
>Do you prefer that I will attach the files: /etc/dfstab /etc/mnttab and /etc/exports?
We mostly care about /etc/fstab.

Re: auto mount
uname -a shows:
B.11.11 U 9000/785
I attached the file.
