Preparing to transition Solaris host LUNs with Sun Volume Manager

03/25/2021 Contributors Download PDF of this page

Before you transition Solaris host data LUNs with Sun Volume Manager from ONTAP operating in 7-Mode to clustered ONTAP, you must gather information you need for the transition process.

This task applies to copy-based transitions and copy-free transitions.

Steps

Display your LUNs to identify the name of the LUNs to be transitioned:

lun show

 fas8040-shu01> lun show
        /vol/ufs/ufs1                  5g (5368709120)    (r/w, online, mapped)
        /vol/ufs/ufs2                  5g (5368709120)    (r/w, online, mapped)
        /vol/zfs/zfs1                  6g (6442450944)    (r/w, online, mapped)
        /vol/zfs/zfs2                  6g (6442450944)    (r/w, online, mapped)

On the host, locate the device file name for the LUN:

#sanlun lun show

The device file name is listed in the device filename column.

# sanlun lun show
controller(7mode)/                    device                                            host                  lun
vserver(Cmode)       lun-pathname     filename                                          adapter    protocol   size    mode

List and record the SVM, and then get the disks associated with the SVM:

metaset

metaset -s set-name
