mount point deallocate & re-allocate

[Kranti Mahmud]

Hi All,

I allocated 130GB of Storage (EMC CX Series) space to my SAP test server (rp3440, HPUX-11i). But now these space is not in use and our SAP team request me to unmount the lvol /oracle/BID from test and to distribute this 130 GB in following lvols of SAPQAS server (rp7420,HPUX-11i):

/oracle/QAS/sapdata1
/oracle/QAS/sapdata2
/oracle/QAS/sapdata3
/oracle/QAS/sapdata4
/oracle/QAS/sapdata5
/oracle/QAS/sapdata6

Can someone give me the procedure to do so?

# umount /File_system from SAP test server

# lvremove /dev/vgxx/lvolxx

# vgreduce /dev/vgxx /dev/dsk/cxtxdx

# vgexport /dev/vgxx

(Request storage admin to unasing LUNS from
(rp3440, HPUX-11i) represent LUNS 130GB to (rp7420,HPUX-11i)

once LUNS are been presented to (rp7420,HPUX-11i)

pvcreate /dev/rdsk/cxtxdx

vgextend /dev/dsk/cxtxdx -> existing vg were above mentioned File system exists

vgdisplay /dev/vgname -> Check space added

lvextend -L /dev/vgxx/lvolxx

fsadm -f vxfs -b M /oracle/QAS/sapdata1 - 6
