MSM storage options
The following points are listed:
• A mixture of node pairs with single and double packs is
supported.
• Either 150- or 200-hours storage capacity per disk is
supported and is controlled by keycode. However,
150- and 200-hour packs cannot be mixed on a system.
• To enable a 200-hour storage size, a system must have
2-Gbyte disk drives on its SPN nodes.
• For both 150- and 200-hour packs, an MSM system may
be expanded from single to double packs by an online
storage expansion through the TOOLs level by selecting
the storage expansion option. For more information see
System Administration Tools Guide (NTP 555-7001-305).
