HOWTO - HPSS FUSE client machine

• 1. yum install fuse.x86_64
• 2. yum install fuse-libs.x86_64
• 3. Install hpss rpm's
  • cd /vo/gridka/install/HPSS7.4.3p2
  • 4. [root@f01-151-104-e HPSS-7.4.3p2]# ls -l hpss*
  • -rw-r--r-- 1 root root 794028 Feb 6 14:26 hpss-clnt-7.4.3.2-0.el6.x86_64.rpm

• • rpm -ivh *
• 6. ln -s /hpss_src/hpss-7.4.3.2-0.el6 /opt/hpss

• NOTE: steps 7, 8, 8.1 only for the first GridKa machine
• 7. Request a service account for GridKa: scc-dcache-0001
• 8. Define the gridka principal scc-dcache-0001 in HPSS /*done by HPSS administrator*/

    /opt/hpss/bin/hpssuser -add scc-dcache-0001 -unix -ftp -home /hpss/gridka -hpsshome /hpss/gridka -shell /sbin/nologin 
    -uid 220618 -gid 12345 -password XXXXXXXX -unixkeytab /var/hpss/etc/scc-dcache-0001.unix.keytab 
    -group "SCC-users-idm" -fullname "dcache-to-hpss"

• 8.1 Update HPSS principal's password
  • [root@hpsscr ~]# /opt/hpss/bin/hpss_unix_keytab -f /var/hpss/etc/scc-dcache-0001.unix.keytab -P update scc-dcache-0001
    • >>>enter the password
• 9. Create an user on the client machine, user: dcache with the same uid and gid as in hpss
  • adduser -m -d /home/dcache -u 220618 -g 12345 -s /bin/bash -p XXXXXXXX -c "dcache-to-hpss" dcache
  • passwd dcache /*put it encrypted in /etc/shadow*/
    • >>>enter the password
• 10. Put the HPSS machines in /etc/hosts /*will be inserted in DNS*/
