Query regarding FS mount point options

Hello,

 

I have to create and  mount SAP filesystems with following options

 

largefiles,mincache=direct,convosync=direct,cio,delaylog,nodatainlog 0 2

 

But I dont have Online JFS and the OS is 11.31.

 

So just want to confirm.  is this True.?

 

And how do I check whether Filesystems on other Servers are mounted with same options. Will fstyp show me the details ( I dont have a HPUX server at hand right now to check,  so please help)

hi,

 

yes, i guess you need online jfs to use cio options. Verify with swlist commands.

 

If OnlineJFS is installed, proceed to create new logical volume

# lvcreate -L 10240 -n lvdata /dev/vg01

 

Create new filesystem

# mkfs -F vxfs -o largefiles /dev/vg01/rlvdata

 

You could try with adding below entries in /etc/fstab.

/dev/vg01/lvdata  /data   vxfs   largefiles,mincache=direct,cio,delaylog,nodatainlog 0 2

 

Mount it

# mount /data

 

You can check if other servers mounted by verifying their /etc/fstab entries or from `mount` command.

These options require the optional (but I think they should be mandatory for production database servers) product Online JFS. If you're spending the money to run SAP, you should invest in Online JFS (new mount options and online lvol resizing), Glance PlusPak (performance monitoring) and if you have any JBOD storage, get Mirror/UX. To see which of these products are installed on any system, use swlist:

 

# swlist | grep -ie onlinejfs -e glance -e mirror
  B2491BA     B.11.31          MirrorDisk/UX (Server)
  B3701AA     C.05.00.050   HP GlancePlus/UX Pak for 11.31
  B3929FB      B.05.00.02     OnlineJFS for Veritas File System 5.0 Bundle

 

 

The command  mount -p will show you the current mount options.
