Table 2-9 Resources to Monitor for RAID Arrays

/vg/

vgName

pv_summary

This gives you an overview of the status of the

entire physical volume group and is recommended

when using EMS in conjunction with ServiceGuard;

see “Rules for Using the HA Disk Monitor with

ServiceGuard” on page 36.

vg/

vgName

pv_pvlink/

status/*

This gives you the status of each PV link in the

array and is redundant to pv_summary. It is

recommended when using EMS outside of the

ServiceGuard environment, or if you require

speciﬁc status on each physical device.

vg/

vgName

lv_summary

This gives you the status of data availability on the

array.
