Question

A volume group is mirrored to two external storage systems. One of the storage systems is rebooted for maintenance. After the storage system is up and available, Isvg shows a disk in a missing state:

What command will change the PV STATE from missing to active?

Accepted Answer

A. varyonvg The varyonvg command re-activates a volume group and during that process scans for all defined physical volumes. When a previously missing disk is once again accessible, varyonvg updates the PV STATE to active and restores I/O paths, making it the correct command to bring the VG back to a fully operational mirrored state.

Answer

B. chpv chpv modifies physical volume characteristics such as allocation permission but does not resolve a missing PV state caused by a storage outage.

Answer

C. cfgmgr cfgmgr reconfigures device drivers and detects new hardware but does not change the logical PV state within a volume group definition.

Answer

D. chdev chdev changes device attributes at the ODM level but does not affect the PV STATE tracked by LVM.

Answer

E. syncvg syncvg synchronizes stale logical volume mirrors but requires the PV to already be active before it can operate.
