Write failed: Broken pipe --------- Issue.

while we try to  ssh from one server to another and we receive above error.

newcqa@cde-app-xx.abc.com:/x01/newcqa23>ssh tomcat@172.25.72.168
Write failed: Broken pipe


first we check with the original server and there is no issue with that, and we switch to the second one..


then we find that we can't switch to the user on the 2nd server. 

 [root@exp-tomcat ~]# su - tomcat
su: cannot set user id: Resource temporarily unavailable


issue with resource limit exceed for tomcat user in the server. 

them we increased the resource limit. 


vi /etc/security/limits.conf

add below entry..
 
tomcat          soft     nproc          2047
tomcat          hard     nproc          16384
tomcat          soft     nofile         1024
tomcat          hard     nofile         65536

Then issue resolved.

MOUNT USB HDD/USB PEN DRIVE IN SOLARIS 10

MOUNT USB HDD/USB PEN DRIVE IN SOLARIS 10

Assuming system disabled the auto mount option.
How to check auto Mount is disable or not:

Check whether  volfs is running or not..
root@PHM1SVEWBSCSDB # svcs -a|grep volfs
maintenance    11:55:11 svc:/system/filesystem/volfs:default

****************** if it is in maintenance mode*****************

cat /var/svc/log/system-filesystem-volfs:default.log 

Manual method... 

root@PHM1SVEWBSCSDB# svcadm clear volfs 

root@PHM1SVEWBSCSDB #svcs volfs 

STATE STIME FMRI offline* 22:17:30 svc:/system/filesystem/volfs:default 

root@PHM1SVEWBSCSDB # svcadm enable -s volfs 

root@PHM1SVEWBSCSDB #svcs volfs 

STATE STIME FMRI online 22:17:42 svc:/system/filesystem/volfs:default 

**********************************************************************
if it is disabled, enable it for enable auto-mounting option.

# svcadm enable volfs

If the  usb flash is recognize by the system it will be mount and you  can see the
status with

root@PHM1SVEWBSCSDB # rmformat -l

For mount USB HDD
set the default solaris partition up (pick the default prompt here)
# fdisk /dev/rdsk/[device_name]
get the number of sectors in the disk (look for the 'Sector Count' column)
# prtvtoc /dev/rdsk/[device_name]
make a ufs filesystem on the device
# newfs -v -s [sector_count] /dev/rdsk/[device_name]
make a mountpoint
# mkdir /usbdrive
mount the formatted disk (note that we no longer use the raw disk here (rdisk))
# mount /dev/dsk/[device_name] /usbdrive
 To find under what names file systems are mounted:  use the
root@PHM1SVEWBSCSDB #df -k
