Pinned topic NFS mount settings on HP-UX

‏2012-09-05T08:48:22Z |
In our environment vobs and views storages are mounted on HP-UX servers via NFS.
These are the current mount settings:

pccmop05:/change_manag/rls /change_manag/rls nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
pccmop05:/change_manag/porting /change_manag/porting nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
pccmop05:/change_manag/procedure /change_manag/procedure nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
pccmop05:/change_manag/compila /change_manag/compila nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
pccmop05:/change_manag/import /change_manag/import nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
pccmop05:/change_manag/CCUCM /change_manag/CCUCM nfs wsize=2048,rw,suid,soft,bg,retrans=2 0 0
ccase01:/ccase01 /ccase01 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
ccase02:/ccase02 /ccase02 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
ccase03:/ccase03 /ccase03 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
ccase04:/ccase04 /ccase04 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
ccase05:/ccase05 /ccase05 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
ccase06:/ccase06 /ccase06 nfs wsize=4096,bg,rw,suid,soft,retrans=2 0 0
fsharafs01:/vol/vol_ARA_Prod /home/vobadm/ARA nfs bg,rw,soft,retrans=2 0 0

Are they correct and/or recommended for ClearCase?
I found nothing about them in the infocenter.
Our CC version is 7.1.2

    I'll only comment on the 'soft' option, and in fact hoping for confirmation...
    IIRC soft mounts used to be strongly discouraged.
    ClearCase commands are/were not prepared to cope with or even report underlying failures.
    Maybe this recommendation should be better scoped...

    I asked the IBM support about this issue.
    Officially, there are no recommended read/write size settings for the Clearcase file systems (for vobs and views).
    The ClearCase filesystem just matches the settings that are set/defined on the OS.
    Whatever value for these can be used to match the work environment.
    Generally, these values are set between 1k and 8k.
