The process of adding a physical disk to GPFS

Process 1 of adding a physical disk to GPFS. Create a temporary file [root @ sdcmpdb1 ~]. # Vi/tmp/nsdprofile2 emcpoweri: dataAndMetadata: emcpowerj: dataAndMetadata: emcpowerk: dataAndMetadata: emcpowerl: dataAndMetadata: emcpowerm: dataAndMetadata:: 2, generate nsd disk mmcrnsd-F/tmp/nsdprofile2 [root @ sdcmpdb1 ~] # Mmcrnsd-F/tmp/messages: Processing disk emcpowerimmcrnsd: Processing disk category: Propagating the cluster configuration data to all affected nodes. this is an asynchronous process. 3. view the current nsd disk [root @ sdcmpdb1 ~] # Mmlsnsd File system Disk name NSD servers export gpfs_lv gpfs1nsd (directly attached) gpfs_lv encrypted (directly attached) (free disk) encrypted (directly attached) gpfs5nsd (directly attached) (free disk) gpfs6nsd (directly attached) (free disk) gpfs7nsd (directly attached) (free Disk) gpfs8nsd (directly attached) 4. Add nsd to the gpfs file system. Note that the corresponding gpfs_lv is the file system name found in the preceding step [root @ sdcmpdb1 ~]. # Mmadddisk gpfs_lv-F/tmp/nsdprofile2 The following disks of gpfs_lv will be formatted on node sdcmpdb1: gpfs4nsd: size 146801280 KB gpfs5nsd: size 146801280 KB failed: size 146801280 KB gpfs8nsd: size 146801280 KBExtending Allocation MapChecking Allocation Map for storage pool systemCompleted adding disks to file system gpfs_lv.mmadddisk: Propagating the cluster configuration data to all affected nodes. this is an asynchronous process.
