The virtual LDEV ID (0x4444) is assigned to the P-VOL (LDEV ID: 0x4444) and the In this case, you do not need to delete the quorum disk. The volume is not accessible if a failure occurs while the S-VOL pair status is COPY, SSUS, or PSUE. The new Consistency Check feature is very useful and very popular functionality in SnowMirror 3.2. GAD reserve attribute is assigned to the P-VOL and the S-VOL by using the For a normal volume, global-active device operations. When the GAD status of the pair changes to Quorum disk blocked, the P-VOL I/O mode remains Mirror (RL), and the S-VOL I/O mode changes to Block. MirrorView is easily configured and managed from within EMC’s Navisphere®management software.
