HP 3PAR Solaris Implementation Guide

Check the new size:
# df -k /mnt/test
Summary:
• Create and export the initial LUN
• Scan the device tree on the host
• Run 'format' to configure the LUN (set type and label)
• Create and mount the file system on the host
• Grow the LUN on the HP 3PAR StoreServ Storage
• Rescan the device tree on the host
• Unmount the file system on the host
• Run 'format' to reconfigure the LUN (set type and label)
• Mount and grow the file system
Growing a VxVM Volume
The vxdisk resize command can update the VTOC of the disk automatically. It is not necessary
to run the format command to change the length of partition 2 of the disk in advance.
A disk group must have at least two disks to perform the DLE operation since the disk is temporarily
removed from the disk group and it is not possible to remove the last disk from a disk group. If
there is only one disk in the disk group, vxdisk resize fails with the following error message:
VxVM vxdisk ERROR V-5-1-8643 Device Disk_10: resize failed: Cannot remove last disk
in disk group
WARNING! Always refer to the Veritas release notes before attempting to grow a volume.
Host - Sol 10 MU9
Stack - SSTM with emlxs
File System - VxFS
1. Create two LUNs (minimum) on the HP 3PAR StoreServ Storage and export to the host:
# createvv <cpg_name> <lun_name1> <size>
# createvv <cpg_name> <lun_name2> <size>
# createvlun <lun_name1> <LUN_ID1> <host_name>
# createvlun <lun_name2> <LUN_ID2> <host_name>
2. Scan the device tree on the host (other commands are required for different HBA drivers):
# cfgadm -o show_FCP_dev -al
# luxadm probe
# devfsdam
# vxdctl enable
