问题

Solaris 平台 NetBackup master server变更IP地址后，无法在master server上登录Java Administration Console。

原因

Master server更改IP地址后，更新主机名称解析文件/etc/hosts,重启NetBackup 服务，进程状态正常。然而登录本机Java Administration Console失败，报告无法连接server。
1.执行命令/usr/openv/netbackup/bin/bpclntcmd -pn,结果仍然返回原IP址址。

2. 执行命令/usr/openv/netbackup/bin/bpclntcmd -clear_host_cache,清除host name cache，执行命令正常中止无报错信息，重新启动OS。

3. 执行命令/usr/openv/netbackup/bin/bpclntcmd -pn,结果仍返回原IP地址。

4.执行命令truss -aefo /tmp/bpclntcmd.txt  /usr/openv/netbackup/bin/bpclntcmd -clear_host_cache,发现如下信息,
munmap(0x2ad6e5831000, 4096)            = 0

) = 205
exit_group(0)                           = ?
Process 21568 detached

5. 检查发现在/usr/openv/var/host_cache的文件中还是记录原IP地址。

解决方案

1. 删除/usr/openv/var/host_cache目录的所有内容,重启NetBackup服务，NetBackup将自动重新生成cache文件。
2. 执行命令/usr/openv/netbackup/bpclntcmd -pn 输出中新IP地址已经变更。
3. 重新登录Java Administration Console。
