HP-UX Reference (11i v2 04/09) - 1M System Administration Commands N-Z (vol 4)

vgscan(1M) vgscan(1M)

If for some reason, there is a need to re-construct

/etc/lvmtab when the system is running production

application,

vgscan will create a partial /etc/lvmtab

. In this case, most of the primary paths should

be included in the

/etc/lvmtab. Use vgextend

to include any missing alternate paths in the VG.

EMC DISK WARNINGS

Starting at 10.20, the

vgscan command is supporting additional EMC Symmetrix disk product func-

tionality (see vgchgid(1M)). The vgscan command will be enforcing a new rule such that only EMC

disks with the same attributes can belong to the same volume group. Note that an EMC disk, without any

of the additional attributes, can still be mixed with non-EMC disks in the same volume group. Please

consult your EMC Symmetrix documentation, if applicable.
