Scheduling any job at filer

 

From windows host ( admin host ), enable rsh ( windows 2003 box )

C:\> rsh sim –l root –n sysconfig –r    gave the output result ( sim is filer )

 

Filer http access

1. license http

2. httpd.enable ON

3. httpd.rootdir xxxx ---- location like /vol/vol0/<share path or

                                         qtree >

 

Volum performance Optimization

P/W

To change admin host administrator’s p/w

Filer>passwd

Filer>login administrator

Filer>new password:…..

 

To change root p/w

1. attach to console – straight console

2. press Ctrl-C while booting

3. On the menu choose option 3 – password change  - root

 

Ctrl-C  - boot menu options

1. Password reset   ---  root

2. Disk Initialize and destroy and setup new filer

 

New filer setup

Software get url –f filename

Software install url

WAFL stuffs

 

Vol walf iron   - checks the vol in wafl level

Wafl check  ( when inconsistencies happen, when vol

                       becomes restricted all of a sudden )

                to correct for inconsistencies volume

                1. Ctrl –C while boot

                2. Options – Selection ? WAFL_Check -z

 

 

For slow access or backup or performance issues

Filer> wafl scan masure_layout      vol0

Filer> wafl scan measure_layout /vol/vol0/filename

Filer > wafl scan status [vol|file]    ---- to view

 

 

NFS General

 

/etc/exports

 

/vol/test    -rw,root=sun1

/vol/vol1    rw,root=sun1

 

#mkdir /mnt/filer

#mount filer1:/vol/vol1 /mnt/filer

 

/etc/rntab  - maintains the mount point

/etc/hosts   - name and IP address

/etc/nsswitch.conf  - resolution order file

Filer> exportfs

Filer > rdfile /etc/exports

filer> exportfs –a

filer>exportfs –I –o rw=<ip address>, root=<ip address>

 

NFS troubleshooting

 

 

 

Wcc –u  <unix user>   ---------- unix credential

>exportfs -c host pathname ro|rw|root #checks access cache

                    for host permission

>exportfs -s pathname # verifies the path to which a wol is

                     exported

>exportfs -f #flush cache access entries and reload

>exportfs -r #ensures only persistent exports are loaded

 

NFS error 70 - stale file handle

>vol read_fsid

 

# mount   --- will display what protocol being used for mounting    ( in unix host )

 

# mount –o tcp < >

While changing the mode

chmod 4710 oidldapd

chmod: changing permissions of `oidldapd': Input/output error

 

If I look in /var/log/message I see the following error:

Mar 30 19:44:59 bilbo kernel: nfs_refresh_inode: inode number mismatch

Mar 30 19:44:59 bilbo kernel: expected (0x950485c3/0x9b7609), got (0x950485c3/0x7d0b11)

 

Told customer to get rid of the nosuid on the exports file and that solved the issue.

 

Permission Denied : File handle

67000000   6ad77710  20000000  107754a 99f750f  84ce0064  67000000   6ad77700

 

First two numbers FSID

Next three  :  FID, Inode, FID

Next three :  FID export point

 

Now, inode is different for different volume

It is found by

 

Priv set diag

Vol read_fsid vol0

 

 => gives hex number – should match any number above so that it indicates, file of which volume has problem. Hex number can be converted to decimal value as well

 

In unix side

# find –inum <decimal value >

# find /mnt/cleearcase –inum  _________

  ( checking FID for above mount point )

 

# /etc/mnttab 

  ( look here to find that number as well )

 

# ls – li   prints inode numbers – in decimal – convert that to

                hex

# find . –inum < number > print  

 

( Sometimes, vol fsid number found must be reversed to get the exact place of innode )

 

General Permission Problems

Check the export permissions

Check the local unix system – file level and owner level

                     Permission and also qtreee security

( Sometimes filer permission comes to stay on top of local permission at unix box, so that it cannot be seen – they will become hidden )

To find use

# chmod

#chown

 

Read unix files

# cat

# more

# vi

 

NFS Performance

 

Pktt – start e5a , -dump e5a, pktt –stop ( all three– start to end)

Sysstat

Nfsstat –d  ( displays cache statistic )

             -z  ( zero out the stat )

             -m  ( mount point statistics )

Perfstat –b –f filename > perfstat.begin

Perfstat –e –f filename > perfstat.end

# time mkfile 10m test   ( time it takes )

# time cp test

Windows host > sio_ntap_sol 100 100 4096 100m 10 2 a.file

                           b.file –noflock

 

CPU utilization 100 percent

 

Customer needs to collect and send

Perfstat –f  <file name> -t 5 > perfstat.out

 

More detail perfstat

Perfstat –t 2 –f nasx > text.txt

Perfstat –t 2 –f nasx –P flat > text.txt

                                  -P  domains ( SMP )

                                       ~ flat

                                          ~ kahuna

                                          ~ network

                                          ~ raid
