You can check the device file and LDEV numbers for device files constituting a file system by issuing the
horc_devlist command in the NAS package in which the P-VOL is connected (see Table 46 ). Compare
this with Table 45 . For information about the horc_devlist command, see the NAS Backup Restore
User's Guide.
Table 46 Checking device file and LDEV numbers of P-VOLs

You can also check the device file and LDEV numbers for unused device files that can be S-VOLs by issuing
the horc_devlist command in the NAS package in which the S-VOL is used. Compare this with Table 45 .
Table 47 Checking device file and LDEV numbers for unused device files that can
